Understanding Alpha Gal Syndrome
Could I be experiencing Alpha Gal Syndrome? Previous tests have confirmed I do not carry allergies to Alpha Gal, beef, or pork. However, I do have a class 3 allergy to tomatoes, along with class 1 sensitivities to both milk and lamb. My allergist suggested that it’s possible to have Alpha Gal and still test negative for it. Is this a legitimate concern? Additionally, I deal with Autonomic Dysfunction, and for the past year, I have experienced spontaneous hives and episodes of flushing. Last year, I underwent tests in May and August after a tick bite in May, and both results indicated negativity for the allergies in question. I am a 27-year-old woman weighing 142 pounds.

It's understandable that you have concerns about Alpha Gal Syndrome (AGS), especially with your ongoing symptoms and allergy history. Let's break this down to clarify your situation.
Main Points:
- Alpha Gal Syndrome Overview: AGS is a condition where individuals develop an allergy to galactose-alpha-1,3-galactose, a sugar found in red meat and some other animal products, often triggered by tick bites.
- Testing Limitations: It’s true that some people can experience AGS symptoms without testing positive for the allergy, especially if tests were conducted shortly after being bitten by a tick.
- Other Symptoms and Conditions: Your symptoms, including hives and flushing, may overlap with AGS but can also be attributed to other conditions, especially given your autonomic dysfunction.
Explanation:
Although you have negative test results for AGS, this does not completely rule it out, particularly if you recently had a tick bite and your symptoms suggest a potential allergic reaction. Additionally, your class 3 allergy to tomatoes and sensitivities to milk and lamb could indicate a predisposition to allergies in general, which complicates the picture.
Your autonomic dysfunction might also contribute to the spontaneous hives and flushing episodes, as such conditions can lead to dysregulation of the immune system and skin responses.
Next Steps:
- Monitor Symptoms: Keep a detailed diary of your symptoms, noting triggers, timing, and any correlation with food intake or environmental factors. This can provide valuable information.
- Consult Your Allergist: Since your allergist has raised the possibility of AGS despite negative tests, it may be worthwhile to have a follow-up conversation focused on this diagnosis. If you experience new or worsening symptoms, bring this information to their attention promptly.
- Consider Allergy Testing: If symptoms persist or develop, retesting for AGS or a comprehensive panel for other potential allergies might be advisable.
- Stay Informed: Research AGS, including symptoms, possible dietary changes, and management strategies. This knowledge can help you in discussions with your healthcare providers.
Your health and comfort are paramount, so continue to advocate for yourself as you navigate these complex symptoms and their underlying causes. If you have further questions or need more clarification, feel free to ask!

Navigating Post-Sepsis Challenges: Seeking Guidance
In October, my 71-year-old mother, who has multiple sclerosis (MS) and experiences mild cognitive impairment related to her MS—not dementia—contracted sepsis. This dire situation began when she fell in the bathroom, severely injuring her right calf and affecting her kidney. Throughout her life, she has dealt with urinary tract infections (UTIs) due to her MS, yet she had never encountered sepsis until this incident. Additionally, she was also contending with cellulitis, a condition she has battled in the past. After spending two days in intensive care, she transitioned to a regular hospital room for approximately two weeks. Following her discharge, she was transferred to a rehabilitation facility to focus on regaining her mobility, where she remained for about a month. Unfortunately, since her experience with sepsis, she has been unable to walk, becoming entirely bedbound—an unimaginable change for a woman who was once quite active, walking daily. Moreover, she has been affected by intense delirium; the impact of sepsis has exacerbated her pre-existing health conditions to the extent that she required placement in a long-term care facility. It has now been four months since her hospitalization, and she has not regained the ability to walk, with her delusions still being exceedingly distressing. She expresses fears that people want to harm her and that I too am in danger; it's heartbreaking to witness. I do my best to comfort her with reassurances of safety and love, but these reassurances seem to fall short. It feels as though a switch has flipped in her mind—one moment she was coherent, and the next, everything had changed. I feel apprehensive about her future; I struggle to envision her recovering, and I fear for the continued deterioration of her mental well-being. My heart aches for her situation, and I often feel powerless. A friend of mine, who works as an EMT, suggested that it’s possible my mother could have experienced some level of oxygen deprivation to the brain when she went septic on that day, possibly leading to long-term or even irreversible damage. I am reaching out to see if anyone else has been through a similar experience or knows someone who has? I would greatly appreciate any advice or insights you may have.
Managing Chest Pain and Job Concerns
At 23 years old, I found myself in the hospital recently due to experiencing chest discomfort, dizziness, headaches, as well as pain in my neck and shoulders. After a thorough examination, I was diagnosed with myocarditis. Fortunately, there were no indicators of a heart attack, though my troponin levels were alarmingly high—well over the normal range of 60s, reaching around 600 upon my arrival, and peaking at 1,400 overnight. The medical team prescribed me 0.6mg of colchicine to combat inflammation and advised me to take things easy. However, despite my request, they did not provide a note to confirm my work limitations. This leads to my current dilemma: my employer requires a doctor's note to validate restrictions on my ability to handle certain weights. Because the doctors believed I would recover quickly, no documentation was issued regarding my capacity to work. Now, even though my chest pains have diminished since the initial episode, they intensify when I engage in any strenuous activity. Additionally, I experience frequent lightheadedness when I rise from a seated position, along with headaches triggered by simply tying my hair back. I worry that I might be exaggerating my symptoms. I genuinely enjoy my job, but I am not willing to jeopardize my health for it. I’m contemplating whether to resign or perhaps switch roles to a cashier position, which seems less strenuous. Nevertheless, continuing to work while dealing with increasing pain is a concern, especially considering the financial aspect. Should I return to the hospital for reevaluation, or is it wiser to wait and see if my condition improves with the prescribed medication?
Feeling Nauseous and Dizzy After Dining Out
I’m a 23-year-old woman, around 160 pounds and 5 feet 6 inches tall. Currently, I’m using birth control and taking Pristiq. Lately, I’ve been feeling quite confused and could really use some guidance. For the past two to three years, I have experienced sudden bouts of severe nausea and dizziness, often feeling as though I might faint after eating out at a restaurant. Strangely, this phenomenon never occurs when I eat at home. The episodes seem completely unpredictable. I can consume the same carb-heavy meals at home without any issues. Despite having a history of anxiety which has been managed, I’ve never considered that anxiety might influence my dining experiences in public. More often than not, I find myself needing to leave the establishment and step outside, which helps alleviate my discomfort. Routine blood tests have shown no abnormalities. I have undergone both an endoscopy and a colonoscopy. While I was diagnosed with non-severe Barrett’s esophagus, the specialist did not indicate any signs of GERD. Given my situation, I’m contemplating a visit to a holistic practitioner since I truly enjoy dining out and am feeling quite desperate for a solution. I would greatly appreciate any suggestions you might have!
Navigating the Challenges of Idiopathic Pulmonary Fibrosis: Insights and Queries
During the summer, my husband, who is in his early 60s, experienced significant breathing difficulties, prompting me to take him to the emergency room after several days of coping with the issue. There, he was diagnosed with pneumonia and atrial fibrillation (afib) and spent 3.5 days in the hospital. Doctors removed 2.5 liters of fluid from his right lung while treating his afib. By late August, after multiple CT scans and extensive blood tests, he received a subsequent diagnosis of idiopathic pulmonary fibrosis (IPF). In September, he underwent cardioversions and ablation procedures for his afib, successfully restoring him to a normal heart rhythm. Although he was provided with supplemental oxygen during his hospital stay, he hasn’t been prescribed oxygen therapy at home, though he does connect it to his CPAP machine for nighttime use. Attached to a second opinion report from our doctor in January is this pulmonary function test data: Visit Date FVC FEV1 DLCO_SB FRCpl TLC RV 1/6/2026 3.36 2.96 10.41 2.55 4.76 1.40 8/26/2025 4.59 3.51 2/11/2016 4.92 4.20 32.14 Here are a few additional points to consider: - During the January 2026 tests, my husband was suffering from intense back pain, which we suspect is due to a herniated disc that may ultimately require surgical intervention. Could this pain have an impact on his respiratory function or influence the test results? Might his forced vital capacity (FVC) have been closer to the higher value of 4.59 had he not been experiencing such discomfort? The technician was aware of his back pain and noted in the report that the spirometry data was acceptable, accompanied by good effort throughout the test, yet I still find myself questioning. - His chronic cough started in 2019, well before the onset of the pandemic, and despite seeking medical advice, the diagnosis of IPF was not mentioned at that time, despite a CT scan (we have been informed that imaging techniques have improved since 2019). Since then, the cough has progressively worsened, particularly noticeable following this past summer. - Additionally, he has lost approximately 25 pounds since early July, with the fluctuation being between 25 and 29 pounds. It's important to note that he started taking Ozempic in July 2024, which didn’t lead to any notable weight changes until July 2025, when he went from around 194 pounds to approximately 174-177 pounds. His weight remained relatively stable during the first year on Ozempic. - The pulmonologist has indicated that they will be referring us to a lung transplant team. While this isn’t an immediate concern, they emphasize the importance of starting preparations. However, we are aware that there might be other comorbidities that could complicate this process. I have several pressing questions: - The pulmonologist urged us not to take the commonly referenced life expectancy of 3-5 years from diagnosis too literally, which I appreciate. However, considering my husband’s lungs may have been developing scarring since at least 2019—when the definitive diagnosis only came in 2025—what implications does this hold for 2026? - The doctor is currently trying to prescribe Jascayd, but due to its newness, we are encountering insurance hurdles. As it stands, my husband is not receiving any treatment for IPF. How critical is the timing of treatment in relation to FDA-approved medications for IPF, given everything I've outlined? His first pulmonologist prescribed Esbriet, which he began, but had to discontinue after a month due to insurance complications. - I understand that each situation is unique and that you may not have complete insight into my husband's medical history (e.g., beyond Type II diabetes, which he manages with Ozempic, there are additional health factors), but could you share what we might expect regarding the progression of this disease? How rapidly does IPF typically advance? - Recently, my husband exhibited shortness of breath, leading to a visit to his doctor on Monday (I am writing this on a Wednesday evening). A chest x-ray was performed but returned inconclusive results, suggesting the possibility of an infection rather than pneumonia, affecting the area of his lungs that shows scarring. He is currently on two antibiotics and seems to be improving, although our pulse oximeter readings fluctuate between 87-92%. Just an hour ago, his reading dropped to 87 from 92, which had been his earlier reading seven hours prior. - As his wife and primary caregiver, I seek guidance on what signs to monitor. I noticed the shortness of breath last week, and I keep a detailed log of his weight changes (which I shared with the pulmonologist, confirming that the IPF could contribute to weight loss due to coughing and the increased effort required for breathing). Besides watching for fatigue and weight loss, what other subtle indications should I be aware of that might signal a concerning change in his condition? I am genuinely overwhelmed and frightened, attempting to manage my stress in order to maintain a positive atmosphere for my husband amidst this challenging situation. I would deeply appreciate any advice you could offer. Please help me understand how best to navigate this ordeal.
Are My Symptoms Indicative of an Impending Stroke? Should I Seek Emergency Care?
At 18 years old, I don’t smoke or drink and am currently undergoing tests for HEDS. For the past two weeks, I have experienced intermittent pain on the left side of my head, with sensations radiating from the back to the top. Initially, I suffered from vertigo, but now I just have periodic bouts of dizziness. Additionally, I’ve been feeling short of breath, and I’ve noticed an increase in ear ringing and visual disturbances, such as floaters and flashes. Recently, while eating, I experienced a sharp pain in both ears. These symptoms began around the 25th or 26th of last month, and I’m feeling anxious that they could signal a stroke. My aunt had a stroke in her thirties, which heightens my fears about my own health risks, especially considering my potential HEDS diagnosis. Am I overreacting, or is it necessary for me to visit the emergency room? Are these symptoms truly representative of a stroke, or would they manifest differently, and is there a possibility that a stroke has already occurred?
