Experiencing Fever and Symptoms After Mosquito Bites in Ecuador: Should I See a Doctor?
Age: 22, Weight: 150 lbs, Height: 5’10” For the last few months, I've been engaged in research in the Ecuadorian Amazon. This isn't my first field experience, and I've been immunized against yellow fever, typhoid, chikungunya, and dengue fever. Currently, I’m taking doxycycline as a preventive measure against malaria, having switched from Malarone due to side effects. In addition, I'm prescribed Adderall (30mg), Lyrica (50mg twice daily), and Ajovy for chronic migraines, which I manage effectively with these medications. I also take a daily multivitamin and use ZyrtecD about four times weekly to combat mold allergies. A little over a week ago, after washing my field pants, I made the questionable choice to wear shorts for dinner. This decision led to what seemed like a swarm of around 100 mosquito bites. I've had my share of bites during my time here, but this was unprecedented. Following that incident, I began feeling extremely fatigued, nauseous, and frequently suffered from headaches. Initially, I dismissed these symptoms as mere tiredness. However, Thursday night, I developed a fever (although I couldn't measure it), experienced severe chills, excessive sweating, and a debilitating migraine that lingered all night. The next day, I took DayQuil followed by ibuprofen, which helped alleviate some of my discomfort during the day, though I still faced persistent headaches, lack of appetite, nausea, and joint pain. In the evening, I opted for NyQuil, but I found myself reliving the previous night’s symptoms, albeit slightly intensified. I continued taking DayQuil and Advil throughout Friday but still felt a bit feverish until around 5 PM, when I noticed an improvement in my overall state, including a regained appetite and diminished headache. Last night, thanks to NyQuil, I managed to sleep soundly. Today, I took DayQuil again and while I still contend with fatigue, some joint pain, and a lingering headache, my condition is markedly better. I'll be flying back to the US on Wednesday. If I continue to recover well, should I seek medical attention upon my return? Is there any possibility I might have picked up an illness that could resurface in the future?

It sounds like you've had a challenging experience with mosquito bites and subsequent symptoms while in Ecuador. Based on what you’ve described, the combination of fever, fatigue, and body aches can be concerning, especially after a significant number of mosquito bites.
Main Points: While your symptoms have improved, it’s important to be vigilant after returning to the U.S. There could be a possibility of mosquito-borne illnesses, even with prior vaccinations and preventive medications.
Explanation: The symptoms you experienced (fever, fatigue, nausea, headaches, and joint pain) following numerous mosquito bites could suggest a range of illnesses, including but not limited to dengue fever, chikungunya, or even potentially malaria. The fact that you're on doxycycline for malaria prevention is a good step, but no preventive measure is 100% effective. It's also possible that your symptoms could be a set of post-viral symptoms following the bites, especially since you’re showing improvement.
Next Steps:
-
Monitor Symptoms: Keep a close eye on any recurring symptoms, especially fever, severe headaches, joint pain, or gastrointestinal issues after returning home. Note any changes to help healthcare providers if needed.
-
Return to the U.S.: Upon your return, if you continue to feel unwell or if any new symptoms develop, it would be prudent to consult a healthcare provider. They may recommend blood tests to check for mosquito-borne illnesses or other infections.
-
Consideration of Travel-related Illnesses: Communicate your recent travel history and symptoms to your doctor. It’s helpful information for diagnosis and treatment.
-
Stay Hydrated and Rest: Continue resting and maintaining hydration. This will support your recovery as you gear up for your return.
-
Keep Medications Handy: If you still need to manage headaches or other symptoms, keep taking your typical medications (like ibuprofen, as you have been) while also avoiding overuse of any cold medications.
Your situation warrants careful observation, but staying aware and proactive about your health is crucial. You are doing well by recognizing the potential seriousness of your symptoms and planning accordingly. Let me know if you need further clarification or support as you navigate your recovery.

Unusual Skin Rash on Baby Boy (14 months old)
Our grandchild developed a skin rash several weeks ago, starting with a small outbreak on his arm that has since spread to various other areas of his body. Based on my past experiences as a mother of four grown children, I don't believe it's impetigo or ringworm; it appears to be more viral in nature. He hasn’t exhibited any fever that we are aware of and he doesn’t seem to be experiencing any itching. We give him a bath each night and have not changed any of the products we use recently. Interestingly, he prefers cooler bath water, as warm water seems to cause him discomfort. I appreciate any advice or insights you might have regarding this situation. Thank you!
Bumps Under the Muscle: A New Concern
Profile: - Age: 28 years - Gender: Female - Height: 5 feet 10 inches - Weight: 130 pounds - Ethnicity: African American - Symptoms duration: 48 hours - Affected area: Upper trapezius muscle - Relevant medical history: Scoliosis - Current medications: SSRI antidepressant and birth control pills Over the past couple of days, I’ve noticed a firm, somewhat circular mass beneath the skin near my trapezius muscle on the right side. Typically, I experience muscle knots due to stress or poor posture, which tend to resolve with regular use of a massage device or a proper massage session. However, this time, my efforts to alleviate the discomfort have been ineffective; the lump remains rigid despite my attempts to break it up. Using a massage gun fitted with a pointed attachment, I noticed it only indenting slightly without changing the firmness of the lump. I’m feeling a bit anxious about this, especially given my age. I would appreciate any advice or recommendations regarding what this could be or how to address it. If necessary, I can share an image for further clarity.
Persistent Neck Discomfort: Seeking Answers and Solutions
At just 18 years old, I have been grappling with a persistent neck stiffness for the past two years. Despite my efforts, I’ve yet to receive a clear understanding of what might be occurring with my neck. To describe my experience, it often feels similar to the urge to crack one’s knuckles, except this sensation in my neck is significantly more frequent. This issue seems to peak during the initial hours of my morning routine. Upon waking, I instinctively try to crack my neck—a practice I can perform—but the relief is short-lived. Within about 5 to 10 minutes, the uncomfortable sensation returns, leaving me in a perpetual urge to crack my neck again. It’s important to note that the discomfort isn’t localized; it affects the left, back, and right aspects of my neck. At times, cracking it can even elicit unnatural feelings accompanied by pain. This perplexing sensation is hard to articulate, but avoiding it does not ease my discomfort. In an effort to identify any underlying issues, I underwent a scan that indicated my neck appeared to be in good health. I have consulted various medical professionals and specialists regarding my issue, however, none have provided a lasting remedy. Looking back, I suspect my neck problems may stem from excessive phone usage in the past and poor posture during school hours. Fortunately, I've made improvements in both areas, and I believe my posture is no longer a contributing factor to these peculiar sensations. I’m reaching out to see if anyone can shed light on what might be causing these symptoms and whether they have any insights or suggestions for managing this ongoing issue?
Navigating My Medical Journey: An Overview
Greetings, everyone! This is 25FTM, standing at 5'7" and weighing approximately 190 lbs. Currently, my medication regimen includes vibryyd, adderall, androgel, valtrex, lamotrigine, seroquel, mirtazipine, omeprazole, and I recently added keppra in late June. Here's a rundown of my health situation from head to toe: **Neurological Issues:** - Detected a vascular malformation measuring about 10mm in the right mesial temporal lobe (April). - Experiencing persistent floaters in my eyes. - Occasionally, I find lesions on my tongue and inside my mouth. - I've noticed clenching of my jaw. **Spine and Musculoskeletal Health:** - Recently diagnosed with mild thoracic endplate changes (June). - I’ve been dealing with bone pain, particularly in my legs since March. - My joints frequently crack and feel stiff and painful. **Cardiovascular Symptoms:** - Diagnosed with sinus tachycardia exhibiting borderline left axis deviation (June). - My heartbeat often feels like a throbbing sensation, perceptible throughout my entire body. **Digestive Health:** - Identified sclerosing mesenteritis (April). - Mild diverticulosis noted in my colon (June). - Experiencing bleeding during bowel movements. - My abdomen often feels uncomfortably bloated. **Dermatological Concerns:** - Developed a sore on my inner thigh (October 2024) alongside intermittent rashes. - Similar rashes have appeared as raised welts under my armpits and seem to flare up with heat/sweating (May/June). - Noticed an increase in petechiae across my body. - I frequently experience itching and a crawling sensation on my skin. - Occasionally, I observe dark red spots on my face and dark red streaks on my inner leg after taking a shower. **General Health Updates:** - Diagnosed with reticulocytosis (April) and mild anisocytosis (May). - I’ve found it challenging to achieve orgasm, with sensations feeling diminished. - Seizures seem to initiate in my abdomen while I remain conscious and continent (11 episodes recorded between May 21st and June 27th, ceased after starting keppra). *An EEG did capture a seizure during light stimulation, which rendered me momentarily speechless but was classified as non-epileptic.* **Medical History:** I've struggled with GERD, syphilis, and have had two concussions in the past. There’s a family history of Lynch Syndrome and gastrointestinal cancers, although my mother does not carry the gene. A CT scan from 2020 identified enlarged lymph nodes on my mesentery, but it wasn’t until March of this year when I became aware of their existence. The ER staff informed me that their size had not changed since 2020, which caught me off guard. Since October 2024, I’ve felt a general decline in my health, with significant weight loss—going from around 215 lbs to fluctuating between 175 lbs and 190 lbs depending on my gastrointestinal situation. I attribute some of the weight change to starting Adderall in March 2024, which might have affected my appetite, but there's an unsettling feeling that something more serious is at play. I expressed these concerns to my primary care physician back in March, sensing a strong indication that something is amiss with my body. Recently, I've shifted to feeling a pressing urgency regarding my health. **Healthcare Engagement:** Since October 2024, I have made a total of 19 visits, not counting specialist appointments. **Consultations with Specialists:** - **Neurologist:** After diagnosing me with PNES, he referred me to a clinic in the city and recommended against pursuing further evaluation for my vascular malformation, deeming my seizure control through keppra as coincidental. - **Gastroenterologist:** Met with a gastro nurse practitioner for the first consultation last week; I’m now set for my first upper endoscopy and colonoscopy on August 5th. - **Hematology:** My primary care provider submitted my referral incorrectly, so I'm still waiting for my first appointment on August 1st regarding potential internal bleeding. - **Ophthalmology:** An uveitis expert diagnosed my dry eyes, advising artificial tears, but discouraged any further investigation. **Planned Treatments:** - Follow up with the PNES clinic in the city. - Attend upcoming endoscopy and colonoscopy, followed by a follow-up consultation in two weeks. - Hematology appointment on August 1st. So, what are your thoughts? Do you think I'm in a precarious position? Are you as eager to hear the results from these tests as I am? The thought that my story might one day contribute to medical literature is the motivation that keeps me going, so I hope you find this journey as perplexing as I do! Take care of yourselves. 🫂 If I can manage ten minutes of gentle yoga in my current state, you can certainly increase your water intake. I believe in our abilities!
Understanding Nephrology Concerns: A Personal Account
I’m a 21-year-old intersex individual, measuring 5’8” and weighing 125 pounds, and I was diagnosed with juvenile systemic lupus erythematosus (SLE). My current treatment regimen includes vitamin D, magnesium, a B-complex, as well as B12, B3, and hydroxychloroquine. I consume approximately 4 to 6 gallons of water daily, as I often experience significant thirst. My tests show a normal A1C level, normal blood glucose, and no ketones detected in my urine, indicating that I do not have diabetes. Additionally, my bladder functions normally, and after consulting with a urologist, the only issue identified was a tight pelvic floor. My blood pressure consistently remains within a healthy range, fluctuating between 90/50 to 120/80. A recent CT scan revealed slight renal atrophy; however, the medical team concluded that this finding was not a cause for concern. Since around the age of 16, my urinalysis results have consistently indicated the presence of protein, white blood cells (WBCs), and abnormal sedimentation (SEC), along with increased turbidity. Cultures have always returned normal results. Initially, my rheumatologist attributed these anomalies to a less critical issue but after observing protein consistently in three separate samples, she decided to refer me to a nephrology specialist. This has sparked worries within me concerning the possibility of developing lupus nephritis. I seek clarity on whether these findings warrant genuine concern or if they can still be deemed within acceptable limits.
