Could a Missed Snake Bite Be the Culprit?
My 92-year-old grandfather has been shuffled between various specialists over the last month due to an alarming set of symptoms including sudden swelling, discomfort, and blistering on his foot. The situation began when he stepped into his garage, experiencing acute pain in his foot. Initially, he thought he had been bitten by a spider, a conclusion that seemed questionable to me. Shortly after this incident, he began to notice significant swelling, widespread bruising, blister formation, and intense pain. Early photos suggested he might have petechiae, but it’s important to note that he was already diagnosed with moderate to severe thrombocytopenia prior to this event and is receiving anticoagulant therapy following a recent stent insertion in his coronary artery. Given these factors, I doubt there was a thorough evaluation of his symptoms or lab results. He was first hospitalized and diagnosed with cellulitis, but after two days, the infectious disease specialist concluded there were no signs of infection and recommended a consultation with a hematologist. The hematologist expressed no worries and advised him to resume antibiotics. Although he has adhered to this treatment for some time, with only limited improvement and increased pain, he ended up being readmitted due to suspected arteritis. The vascular surgeon attempted a stent placement in his leg but stated there was nothing to stent, indicating that his heart wasn’t functioning well enough. Just this week, the cardiologist assessed his heart health and dismissed any concerns about inadequate perfusion. Currently, he is undergoing a tissue biopsy to pinpoint any underlying infectious agent, with plans to modify his antibiotic treatment if necessary, as all previous cultures—both blood and wound—have returned negative. He is feeling drained, frustrated, and in considerable pain. Our family desperately seeks a definitive diagnosis. I can't shake the worry that a potential snake bite could have been overlooked, especially given his age and medical background. Residing on the Texas Gulf Coast, he is in an area where encounters with pit vipers are not unusual. Moreover, he has a complicated medical history that includes a-fibrillation, coronary artery disease with stent insertion, giant cell arteritis resulting in blindness in one eye, and thrombocytopenia. While I am unaware of his precise medications, I know he is taking an anticoagulant, undergoing steroid treatment for GCA, and is currently on antibiotics. Recently, one unit of platelets was also administered to him.

I understand how concerning your grandfather's situation is given his complex medical history and the recent troubling symptoms. You’re correct to want a thorough investigation of any potential underlying causes, including the possibility of a snake bite, especially in a region where encounters with pit vipers are more likely.
Key Points:
- A suspected snake bite should be considered, particularly if symptoms align with venom exposure, but it also may not be the only explanation for his symptoms.
- Other conditions related to his medical history, such as thrombocytopenia and ongoing anticoagulant therapy, could complicate his symptoms and management.
- The process of investigating his condition through tissue biopsies and potential modification of antibiotic treatment is necessary for accurate diagnosis.
Explanation:
Your grandfather's symptoms of swelling, blistering, and pain can be due to various factors, including but not limited to infection, adverse reactions to medications, and complications from his existing conditions (e.g., giant cell arteritis and thrombocytopenia). The presence of petechiae (small red or purple spots caused by bleeding under the skin) is particularly notable in patients with low platelet counts.
While cellulitis was the initial diagnosis, the lack of improvement and the recent discussions regarding arteritis highlight that further evaluation is essential. A snake bite may produce similar symptoms, but without definitive evidence or eyewitness accounts, it could be challenging to confirm this as the cause.
Next Steps:
-
Communicate with the Medical Team: Ensure that the healthcare providers are aware of your concern regarding the potential snake bite. Request that they consider all possibilities, including a review of photos of the initial injury and any observations made about the bite site. Sometimes details can be overlooked in complex cases.
-
Document Symptoms: Keep a detailed record of your grandfather's symptoms, including any changes in his condition, medication effects, pain levels, and responses to treatments. This information can be useful during discussions with the medical team.
-
Enhance Comfort: Encourage him to stay well-hydrated, manage pain with appropriate over-the-counter options as advised by his healthcare provider, and engage in gentle movements as tolerated to avoid stiffness and improve circulation.
-
Follow-Up on Biopsy Results: Remain proactive about following up on the results of the tissue biopsy. If they reveal any specific pathogens or conditions, that could lead to targeted treatment.
-
Seek Additional Opinions: If you feel the current medical team is not adequately addressing your concerns or if there’s a need for a fresh perspective, seeking a second opinion from another infectious disease specialist or vascular expert may be beneficial.
Your grandfather’s health and comfort are paramount, and I hope that with diligent monitoring and communication with his medical team, clarity and relief from his distressing symptoms can be found soon. Please don’t hesitate to reach out again if you have more questions or need further guidance.

Seeking Assistance for Year-Long Bilateral Knee Pain
I am a 23-year-old male, standing at 5 feet 8 inches and weighing 182 pounds. For a little over a year, I have been grappling with bilateral knee pain. Despite consulting numerous doctors and undergoing various tests, I have yet to find definitive answers or relief from this condition. The issue first arose in August 2024, shortly after I began a new position as a veterinary assistant and moved into a third-floor apartment. My daily activity levels increased significantly; at work, I averaged about 4 miles of walking, and I supplemented this with additional recreation—running or walking—at home. This level of physical exertion was not unfamiliar to me, as I had been an active runner for years without any problems. However, one day during my lunch break, I experienced a sudden, intense pain in my left knee. I took a moment to sit down, and the pain subsided, leading me to disregard it. The next day, I continued with my routine without issue until after a workout at the gym. While using the elliptical, the same sharp pain returned, but this time it affected both knees, and it persisted. What followed was a period of excruciating discomfort lasting around three weeks, during which I would rate the pain between 8 and 9 out of 10. Neither over-the-counter medication like ibuprofen or Tylenol nor ice or heat relief provided any comfort. Determined to get to the bottom of this, I sought immediate care where I underwent bilateral x-rays and inflammatory marker tests that revealed nothing atypical. I then found a new primary care physician who suggested physical therapy, diagnosing my condition as likely patellar tendinitis. I committed to six weeks of therapy focused on stretching and various exercises, both at the clinic and at home. This regimen yielded some improvement, reducing my pain to a 5 or 6 out of 10. My physical therapist eventually recommended that I continue my exercises independently, so I persisted with them. However, despite my efforts, my discomfort persisted due to the demanding physical nature of my job, which involved significant walking and squatting. Over time, I had to take multiple leaves from work, and by December 2024, the ongoing pain compelled me to quit my job altogether. Following my departure from work, I observed a gradual decrease in discomfort, bringing my pain down to a 3 or 4 out of 10 by February 2025, likely due to a marked reduction in my daily activity. Fast forward to September 2025: I have undergone an MRI which showed no issues, in addition to numerous blood tests including screenings for autoimmune disorders and rheumatic arthritis, all of which returned normal results. Based on my concerns, I was referred to an orthopedic surgeon who has prescribed exercises to be performed three times a day for the past two months; however, these have not led to any substantial improvement. I remain convinced that my situation is physiological in nature since neither physical therapy nor extensive rest over the past year has yielded any results, and my various imaging and blood tests continue to show normal findings. One particularly troubling symptom has been the sudden redness in my knees during the night, often accompanied by increasing pain. More recently, I have noticed red dots appearing sporadically on one or both of my legs, which move around and fade away, only to be replaced by red streaks that cause significant discomfort. I am desperately seeking someone who may recognize these symptoms as I yearn for clarity on my condition and a resolution, which remains elusive after a full year of distress.
An Unexplained Condition
At the age of 23 and identifying as female, I maintain a lifestyle free from alcohol, tobacco, or illicit substances. Throughout my childhood, I endured numerous instances of head trauma that rendered me unconscious. Remarkably, I have never experienced nosebleeds or experienced any bleeding from my mouth. How can that be? I have vivid memories of these violent episodes, particularly between the ages of 6 and 7. On at least four occasions, I lost consciousness due to these assaults, yet I was never taken to receive medical attention. Upon regaining consciousness, I often experienced altered vision. At times, everything appeared in black and white, while on other occasions I felt as if I could see someone's face in a distorted multitude of fragments. Additionally, a persistent ringing resonated in my ears during these moments. As I transitioned into my preteen years, the physical abuse continued, and I began having epileptic seizures. Compounding this, I experienced involuntary pulsations emanating from the left side of my head accompanied by relentless headaches that did not subside with the use of pain relief medications. My most recent seizure occurred several years ago, and I have an appointment with a doctor next week. I anticipate that he will recommend I undergo an MRI to investigate my symptoms further.
Can an Autoimmune Condition Exist with a Negative ANA Result?
At 36 years old, I am experiencing symptoms that strongly suggest a vascular autoimmune disorder. Despite consulting several medical professionals including my primary care physician, a neurologist, and a vascular specialist, I have yet to receive a clear diagnosis. My testing has yielded mostly normal results, with the exception of an ANA test that came back negative. Although I experience Raynaud's phenomenon, the absence of definitive findings initially led my doctors to dismiss it as a significant concern. Currently, I haven’t been prescribed any medications but am taking some advised supplements, which include B12, vitamin D3, and iron, along with eliminating caffeine from my diet. I inquired with my physicians about the possibility of having an autoimmune condition despite the negative ANA result, yet they seem hesitant to provide a straightforward answer. I understand that Reddit might not be the most reliable source for this query, but I'm struggling to gather the information I need.
Seeking Clarity on Mysterious Neurological Condition
I’m reaching out in hopes of gaining insight regarding my troubling health situation. My weight is 128 lbs, and my age is 28. My existing health concerns include Hashimoto's thyroiditis (well managed), Raynaud’s phenomenon, polycystic ovary syndrome (PCOS), hypertension, sacroiliac joint dysfunction, a repaired aortic coarctation (currently no issues), and gastroesophageal reflux disease (GERD). Doctors have speculated that I may be dealing with hypermobile Ehlers-Danlos syndrome (hEDS) and postural orthostatic tachycardia syndrome (POTS). Currently, my medication regimen includes metoprolol, levothyroxine, and omeprazole. I typically don’t share my medical journey, so I apologize if I come across as disorganized. Last year, I underwent an epidural steroid injection in my spine without realizing I had sacroiliac joint dysfunction, which took a decade to diagnose. Post-injection, I experienced an alarming sensation of a sharp pop in my back, followed by numbness and tingling in my groin area, leading to a hospitalization where any spinal issues were ruled out. Following this, I began to have episodes of leg weakness accompanied by involuntary muscle twitches. I struggled to walk around the house and found navigating stairs particularly difficult. After experiencing a few more of these flare-ups, I sought help at the ER but was sent away from triage after a doctor berated me for my visit. This was unfortunately part of a broader pattern of dismissive treatment. Fearing the epidural had caused a spinal issue, I consulted various orthopedic specialists and eventually a neurosurgeon, but none could provide answers. During this time, I also had low-grade fevers and noted swelling in the right side of my neck, which now feels less relevant. In June, I encountered severe swallowing difficulties, with food getting lodged in four different spots in my esophagus, which resulted in choking on saliva. An emergency room visit led to a chest CT scan revealing fluid in my esophagus and thymus hyperplasia. Despite this alarming finding, an urgent endoscopy a few days later yielded no new information, as I was unable to swallow at the time. By July, additional symptoms arose, specifically facial droop, particularly noticeable around my mouth, prompting another visit to the ER, spurred on by my family’s concern regarding a potential stroke. I also began having adverse reactions to iodine contrast, necessitating steroid pre-treatment before a CT scan. At this point, I felt a drastic weakness and struggled to maintain control over my body, with rapid breathing as a particularly concerning symptom that hadn’t manifested in previous imaging sessions. After a couple of hours in the ER, a doctor informed me I wasn’t trying hard enough during evaluations and discharged me, despite my lack of response and severe facial immobility. My condition peaked in intensity for about a week, with nighttime episodes of gasping for air and notable weakness, although I occasionally felt normal between these episodes. I subsequently consulted with a neurologist who entertained the possibility of myasthenia gravis (MG). Various tests, including acetylcholine receptor (AChR) and muscle-specific kinase (MuSK) panels, returned values below the threshold yet not to zero, leading to a negative classification. Additional tests for dysautonomia and tumor markers also came back negative. A single-fiber electromyography (SFEMG) test was deemed normal, although I felt the neurologist conducting it was critical of my performance due to the ongoing facial drooping. Despite having recently trialed mestinon with positive results—wherein symptoms notably improved, especially when tracked photographically—my neurologist dismissed the relevance of the medication, attributing my breathing troubles to lung-related issues, despite my insistence that they correlate strictly with flare-ups. Currently, I have been diagnosed with small fiber neuropathy based on light sensations in my feet, symptoms I had noticed long before my recent issues. I’ve undergone several investigative procedures, including a standard EMG (which appeared normal apart from a minor anomaly attributed to my stress), a head CT (normal), cervical spine CT (showing minor narrowing and congenital fusion), and a lumbar MRI (slight bulging but within normal limits). Routine blood screenings have mostly shown normal results, with one exception indicating low vitamin D and normal levels of B12 and magnesium. A home sleep study also came back normal, while a chest CT earlier this year revealed slight lung scarring but no thymus hyperplasia at that time. The symptom patterns align quite closely with myasthenia gravis, particularly with increased severity following physical exertion. Even minor tasks like attending meetings leave my hands weak, cause facial drooping, and lead to swallowing difficulties. When I take mestinon, I experience significant relief from my symptoms within about 15-20 minutes. My primary concern revolves around the respiratory symptoms, especially the episodes where I wake up gasping for air. Fluctuations in my condition can occur rapidly—resting for just an hour can alleviate my symptoms somewhat. Although neurological examinations yielded normal results, I've also dealt with episodes of double vision. Could this still indicate myasthenia gravis, or should I be considering other diagnoses? Could small fiber neuropathy explain the effects of mestinon? Navigating this process has been challenging—especially after a second opinion advised I was too complex for their practice—and I feel like I am running out of time. I ceased taking mestinon upon being told I likely don’t have MG, but now all my symptoms have returned, and I find myself entering another flare. I realize I should probably resume the medication, but I’m concerned that if I don’t exhibit symptoms during evaluation, doctors won’t take me seriously. This entire experience has severely impacted my mental health and my overall quality of life. All I want is to find some help and regain a sense of normalcy in my life.
Experiencing New Symptoms After Strep Throat – What's Going On?
(14-year-old male, height: 5’8”, weight: 140 lbs) Three days ago, I woke up feeling utterly exhausted, as if a truck had run over me. I struggled to leave my bed due to a high fever and a painfully irritating throat, accompanied by the unmistakable red patches at the back of my mouth. Later that day, my mother organized a virtual consultation to obtain a school excuse for my illness the following day. During the appointment, the doctor concluded that the symptoms indicated strep throat, and prescribed some medication. Now, fast-forward to today: while my fever has subsided, my throat has unfortunately become more painful. However, physically, I feel almost back to normal. Curiously, I have started to notice many blisters and sores appearing on and around my tongue, as well as inside my bottom lip. There's also something concerning — I have red dots, resembling small developing pimples, primarily on my left arm, with a few scattered on my right. These spots appear to stop just before the area where my arm connects to my torso, and I'm having trouble describing them further. Could these blisters and the red dots on my arm be linked to the strep throat, or might they be unrelated? What could they potentially indicate?
