Years of Illness: A Sister’s Struggle with Mysterious Symptoms
Greetings! Although I usually refrain from sharing personal matters online, I feel compelled to reach out concerning my younger sister, who is a 17-year-old cisgender female, approximately 110 pounds and standing at 5'1". She has been unwell for what seems like an eternity, and I’m hoping to broaden the conversation beyond my initial post in r/DiagnoseMe because I care for her deeply. Since entering high school, we've noticed a disturbing trend: she frequently falls ill, catching cold and viruses at an alarming rate. Additionally, she experiences unexplained fever spikes, sporadic rashes without clear sources, overwhelming fatigue that leads to extended sleep sessions—sometimes as long as 16 hours—and nausea that's often severe, alongside headaches that occasionally manifest as migraines. Her joints are quite flexible, leading to hypermobility, which causes her significant discomfort. For instance, her ability to move her kneecaps and trachea is marked but often accompanied by pain. When she was younger, her knees hurt frequently, but medical professionals brushed it off as normal growing pains. These ongoing issues have caused her to miss substantial amounts of school, often 1 to 3 days weekly, depending on her flare-ups. Interestingly, our mother and grandfather also have joint concerns, but they do not experience the additional symptoms my sister has. We have consulted numerous doctors in search of answers, but it often feels like we’re navigating in circles. One physician even expressed that current medical science lacks the means to adequately assist her, suggesting we could only manage her symptoms. Tests have shown a high ANA count, and while I can't recall all the specifics, there were unusual results connected to immunology. The closest diagnosis offered was fibromyalgia, though it doesn’t fully capture the extent of her condition. It appears her body may be overly reactive, but my medical knowledge is limited. To cope with pain, she takes an extensive array of vitamins, all recommended by our family doctor, including large fish oil capsules. She strives to address her discomfort with home remedies before resorting to over-the-counter medications like acetaminophen or ibuprofen. She relies on heating pads, warm baths, comforting scents, nausea patches, wristbands, and takes long walks when she can manage it. Our family is feeling increasingly exasperated as each year seems to bring about worsening symptoms and more debilitating effects on her quality of life. It’s concerning that such struggles could impede her ability to lead a fulfilling life, especially since she can often become bedridden for an entire day. Additionally, she has suffered from poor eyesight since childhood, was born prematurely, and faced speech development challenges as a toddler—though this latter issue was likely caused by a stressor that was later alleviated.

It's commendable that you are reaching out to find help for your sister. The symptoms you describe—frequent infections, fever spikes, fatigue, joint issues, and others—represent a complex health situation that could be impacting her quality of life significantly.
Summary of Main Points
Your sister is experiencing a range of debilitating symptoms, including chronic fatigue, joint hypermobility and pain, persistent nausea, and episodes of fever and rash. These issues are affecting her ability to attend school and enjoy life, making it crucial to find effective management strategies.
Explanation
The array of symptoms your sister is facing suggests a possible underlying condition that could involve her immune system, connective tissues, or chronic pain pathways. Given the high ANA count and potential genetic links (noting family history of joint concerns), it might be worthwhile to consider conditions like autoimmune disorders or hypermobility syndromes. As you mentioned, fibromyalgia has been suggested, yet her symptoms may extend beyond its typical presentation.
Since her situation has not improved with multiple consultations, it's essential to keep advocating for comprehensive assessments. Conditions like lupus or rheumatoid arthritis, known for causing systemic symptoms and joint issues, might require in-depth evaluation by a specialist, ideally a rheumatologist with experience in complex cases.
Next Steps
-
Comprehensive Assessment: Seek a referral for a second opinion or consult with a rheumatologist specializing in autoimmune disorders and complex illnesses. Ensure they review past tests, including ANA results, and conduct thorough physical exams. New diagnostic tests or advanced imaging might provide further clarity.
-
Symptom Management: While waiting for expert input, enhance her symptom management with structured routines. This might include:
- Regular Hydration: Encourage plenty of fluids to help manage nausea and fatigue.
- Balanced Diet: Continue focusing on nutrition, particularly if she's taking various vitamins; ensuring she's receiving adequate nutrients from a balanced diet is key.
- Pacing Activities: Encourage gentle, consistent activity, such as short walks or light stretching, without overexerting, as this can help manage fatigue and pain.
-
Track Symptoms: Maintain a detailed symptom diary documenting her symptoms' nature, frequency, and any potential triggers. This can provide valuable insights to her healthcare providers and help identify patterns or correlations with specific activities, foods, or stressors.
-
Support Systems: Emotional and psychological support is equally important. Consider connecting with support groups (online or local) for individuals with similar experiences, as this can provide your sister with a community and coping strategies.
-
Educate and Empower: Educate both yourself and your sister about her symptoms and potential conditions. Knowledge can reduce feelings of helplessness and empower her to take an active role in her health journey.
While the road to understand and manage her symptoms may feel frustrating and lengthy, persistence in seeking appropriate medical care and support will be crucial in helping your sister lead a fulfilling life. Please continue to be her advocate and push for the answers she deserves.

Managing Recurring Cellulitis
Hello! I'm reaching out about my persistent struggle with cellulitis, a condition I've been experiencing repeatedly. At just 29 years old, I'm otherwise in good health, but I first encountered this issue after a minor scratch near my ear, followed by a few insect bites. Every time, I've been prescribed oral antibiotics, which successfully resolve the infection, but it seems to flare up whenever I have the urge to scratch my skin. I tend to be a frequent itcher and picker, and following my last bout with cellulitis, my doctor suggested maintaining cleaner nails and avoiding scratching altogether. Despite my efforts to follow this advice and my diligence in keeping my nails clean, I’ve recently experienced another outbreak. I suspect it could be related to a bug bite, and while I might have unintentionally scratched at it in my sleep, it wasn't anything significant. I’m eager to find effective ways to prevent cellulitis from recurring. I already prioritize nail hygiene and try to resist the urge to itch, but I’m wondering if there are specific soaps or hygiene practices that may offer further protection—perhaps something antibacterial that could keep my skin cleaner? I'm feeling frustrated as these episodes seem to be increasing in frequency, and I dislike relying on antibiotics. Any tips would be greatly appreciated!
Persistent Swelling After Medication Use
At 26 years old and having been on testosterone for nearly two years, I recently faced a serious adverse reaction to Minoxidil. Four weeks ago, I began using this medication, but about two weeks later, I noticed significant swelling in my left ankle, big toe, and foot. The discomfort was severe, yet I felt I couldn't afford to take time off work, so I endured it for six days. By the final day of the ordeal, my other foot began to swell as well, accompanied by intense pain. I finally decided to leave work and visit urgent care. The physician there speculated that it might be gout, administered a steroid injection, and advised me to return home. However, my symptoms continued to deteriorate, and the pain escalated to a point where simply standing induced tears.
Seeking Guidance on Persistent Symptoms
Gender: Female Year of Birth: 1980 I have been experiencing tremors, cramps, and tingling sensations along with considerable pain in both my arms and legs, including my fingers. These symptoms have persisted for more than two months. Over the last fortnight, the situation has deteriorated, particularly with my arms entering a state of stiffness (I apologize if my description is unclear, as English is not my first language). There is no indication of fever. Blood tests conducted two weeks ago revealed an elevated level of muscle tissue damage. However, a follow-up test last week indicated that my levels were largely returning to normal. For the past two weeks, I have been prescribed diclofenac and clonazepam, which have alleviated the pain to some extent. My doctor has referred me to a neurologist and a rheumatologist, but the waiting list is lengthy. I am reaching out here for any suggestions or unconventional ideas regarding my situation, which I plan to discuss with my physician.
Concerns About Persistent Eye Issues and Health Anxiety
Greetings, medical professionals. I appreciate your time. I’m a 27-year-old female residing in Canada, currently taking 100mg of sertraline for OCD and generalized anxiety disorder, along with 10mg of Reactine daily to manage allergies. Occasionally, I use a prescription stimulant for ADHD, and while I'm 5'5" and struggle with obesity due to an eating disorder I’m addressing, I haven't weighed myself in some time. I regularly smoke cannabis but do not use nicotine or recreational drugs and only consume alcohol infrequently. In January, I experienced what I initially thought was an eye infection, characterized by itchy, reddened eyelids that were nearly glued shut upon waking and some watering. I attributed this to my cat, as I am allergic, though I remain asymptomatic with Reactine. After two weeks of disregarding the symptoms, I rubbed my eye post-cannabis and noticed a painful sensation accompanied by a transparent lump on my cornea. An optometrist quoted $100 for a consultation, so instead, I visited a walk-in clinic where I was prescribed both Tobradex (eye drops) and Tobrex (ointment for nighttime use). Shortly into the treatment, I began developing itchy red spots on my calves and arms. When I inquired whether this might be a reaction to the antibiotics, the doctor dismissed the connection and attributed it to a new body wash, suggesting I stop the antibiotics—though I remain skeptical of that reasoning. Ultimately, I ceased the medication, and my condition improved gradually. In early March, however, the eye issue resurfaced. It presented with increased irritation, watering, and a thicker yellow-white discharge. I turned to over-the-counter Polysporin Pink Eye Drops, which provided temporary relief but failed to eliminate the infection completely. By March 7, I returned to the clinic but had to consult with a different physician. He questioned the previous treatment of Tobradex and Tobrex and subsequently prescribed Vigamox (Moxifloxacin). Fortunately, this treatment cleared up the infection without causing additional itching or symptoms. Regrettably, the infection returned at the end of May and has continued to recur, albeit with fewer severe symptoms; the thick discharge has become manageable, but the itching persists and is bothersome. Currently, my left upper eyelid feels uneven, as if small bumps are present—possibly two or three—and it's notably itchy at times. Additionally, I sense that the tear ducts in both eyes feel blocked or inflamed, although discharge is still being produced, albeit at a lesser volume compared to when the infection was acute. Thankfully, my eyes no longer completely crust shut. I remain anxious whether this situation points to something more grave than a persistent eye infection. I’m aware that complications could affect my vision in the future, especially since I've previously been told I am at elevated risk for glaucoma, despite my eyesight remaining stable since my teenage years. The prospect of continuously using antibiotics concerns me, particularly since I cannot afford a consultation that costs $100 with an optometrist. In March, I underwent STI testing as a precautionary measure, which yielded no abnormalities. My complete blood count from November also appeared normal. Yet, I can't shake the feeling that something serious might be amiss, possibly even cancer. This anxiety is compounded by my OCD tendencies; I recently became convinced for a period that I had developed skin cancer. I strive to balance being health-conscious without crossing into obsession, but clarity eludes me amid this ongoing situation.
