Seeking Insights on Dysautonomia and Autoimmune Concerns at 18
Approximately four months ago, I experienced an unexpected low-grade fever (around 100°F). Following this, I endured a period of two weeks feeling as if I had caught a severe cold or the flu. Since then, the fever has recurred sporadically. Soon after, I started noticing muscle weakness, unexplained weight loss, gastrointestinal issues, profound fatigue, and discomfort in my muscles and joints. At one point, simply standing for a few minutes made me feel nauseous and lightheaded. Although I can now stand for longer durations, I still struggle with feelings of weakness immediately after getting up, which seems to improve within a few minutes. My limbs frequently feel too weak to engage in activities or too heavy to manage independently. Since then, I’ve also experienced intermittent cold-like symptoms. Eight months ago, in October, I noticed the emergence of an unusual rash on my face, consistently appearing on the right side, sometimes extending to my neck, nose, and forehead. Initially, we thought it was separate from my other symptoms, but the connections remain uncertain. This rash first surfaced while I was taking Zoloft and continued through the use of four other antidepressants, as well as after I discontinued all medicational treatments. I'm unsure if this is relevant to my current condition or not. I have undergone several blood tests and consulted a rheumatologist, who concluded that my situation does not appear to be autoimmune in nature. Currently, the most persistent issues I'm facing include nausea, fatigue, constipation, and muscle weakness. I am reaching out to see if anyone has insights, suggestions, or potential leads. At this stage, I am searching for any new perspectives as I navigate this complex situation!

It sounds like you are experiencing a complex set of symptoms that are understandably concerning. You’re dealing with intermittent fevers, profound fatigue, muscle weakness, gastrointestinal issues, nausea, and a facial rash. Given that you’ve consulted with a rheumatologist and had various tests done, it’s good to know you are actively seeking insights and patterns in your symptoms.
Explanation
Dysautonomia is a term that refers to disorders affecting the autonomic nervous system (ANS), which controls involuntary bodily functions like heart rate and digestion. Symptoms like lightheadedness when standing, fatigue, and muscle weakness may align with dysautonomia. The rash you described, especially since it has persisted alongside other symptoms, warrants further consideration, as it might suggest a systemic issue even if autoimmune conditions were ruled out.
Given the recent onset and combination of symptoms, it still might be wise to consider monitoring for various underlying conditions, including:
- Infections: Chronic infections can sometimes lead to systemic symptoms such as fatigue, fevers, and joint pain.
- Hormonal imbalances or thyroid issues: These can often cause fatigue, weight changes, and muscular symptoms.
- Nutritional deficiencies: Insufficient vitamins or minerals can also contribute to fatigue and muscle weakness.
Next Steps
-
Keep a Detailed Symptoms Diary: Record the frequency, duration, and intensity of your symptoms, including the rash. Note any potential triggers or changes in lifestyle that coincide with symptom fluctuations. This will help you and healthcare providers analyze patterns over time.
-
Monitor Your Blood Work: Pay attention to tests that evaluate autoimmune markers, complete blood count, thyroid function, and vitamin levels (especially B12, D, iron, and magnesium). You may want to follow up on any abnormal results for further evaluation.
-
Explore Dysautonomia: Research autonomic nervous system issues, as dysautonomia can manifest with your symptoms. Consider lifestyle adjustments such as increased hydration, compression garments, and gradual position changes when getting up.
-
Evaluate Mental Health and Stress Levels: Chronic health issues can impact mental health, so consider stress-management techniques or engaging in supportive activities that promote mental wellness.
-
Consider a Multidisciplinary Approach: If symptoms persist or worsen, seek a second opinion from other specialists, such as a neurologist or a specialist in chronic fatigue syndrome/mechanisms of dysautonomia.
Final Thoughts
Your situation is intricate, but by actively tracking your symptoms and exploring these avenues, you may uncover insights that contribute to a clearer diagnosis or management plan. Remember to be gentle with yourself during this process. It's important to prioritize self-care and seek support from trusted friends, family, or support groups as you navigate these challenges.

Experiencing Lymph Node Discomfort After Drinking Alcohol?
At 19 years old, I've been experiencing intermittent dull pain in my right neck lymph node, positioned just beneath my jaw, for approximately a month. Initially, this discomfort appeared after nights out drinking, occurring twice after such outings. Following that, the pain showed up randomly on two additional occasions, and then it emerged again last night immediately after I had some wine—it literally started to ache right after I swallowed. Typically, the pain lingers for about two days before subsiding, but notably, yesterday, I felt pain during the drinking rather than the following morning. I consume alcohol only socially and am not currently unwell; I lack symptoms such as a cold or sore throat. I have been evaluated for potential autoimmune conditions due to peculiar symptoms present over the last year, which may be relevant (I am prescribed plaquenil twice daily), but no conclusions were reached. This specific area seems to hurt consistently without any visible swelling, making it quite bothersome. What steps can I take to address this issue?
Why Are My Toes Turning Red and Swollen?
Recently, I've observed that my toes have developed some concerning symptoms. About a week ago, I noticed that one of my toes had become reddish and somewhat swollen, particularly underneath the toenail. At first, I dismissed it, assuming I must have bumped it against something. However, today I found that the redness and swelling have spread to nearly all of my toes, with one appearing more purplish than red. Remarkably, there is no pain or discomfort associated with these changes. Considering it's winter in my area, I initially thought the cold might be a factor. However, even when I keep my feet warm, the situation hasn’t improved. Additionally, I've observed that the skin on the tops of my feet, especially near the toes, is getting progressively dry, resembling white, cracked skin. Could anyone shed light on what might be going on with my toes? For reference, I am a 24-year-old woman, 5 feet 6 inches tall, and weigh 90 pounds. I do not have any known health issues.
Recovery Update: 6 Weeks After Bunion Surgery
Hello everyone, I wanted to share a quick update on my recovery journey. It's been six weeks since my bunionectomy, and I noticed that the scab on my surgical incision came off a bit earlier than expected. I’m hoping to get some feedback on its appearance. I have been diligently cleaning the area with iodine each night and replacing the bandage on a daily basis. As for my discomfort, it remains consistent with what’s normal for post-operative healing—I haven’t experienced any significant changes in pain. Additionally, I’m relieved to report that I haven’t developed a fever. If you want to see how it looks, I’ll post a picture in the comments!
Brain MRI Findings: A Mixed Bag of Emotions
Greetings, M26. I wanted to share the outcomes of my recent brain MRI, which I have translated into English with the help of chatGPT. Here are the details from the examination: **Overview of the Brain MRI Results:** * There are no lesions occupying space within or outside the brain, neither above nor below the tentorium. * No evidence of newly formed ischemic or hemorrhagic damage. * There are enlarged perivascular spaces (Virchow-Robin spaces) in both basal ganglia, with the largest measuring 8.8 × 7.5 mm on the left. * Overall, the midline structures are centrally aligned. * The cortical surface shows no signs of asymmetry. * A total of 17 demyelinating microlesions are identified in the semioval centers and in the subcortical areas of the bilateral fronto-insular regions, with the most prominent lesion reaching up to 6.5 mm in diameter, presenting a nonspecific, chronic appearance. * The eyes and the contents of the orbits appear normal in structure and signal on MRI. * The cerebellopontine angles are clear and unobstructed. * No signs of aneurysms were observed in the native scan, which lacked the arterial Time-of-Flight (TOF) sequence. * There is mild hypertrophy of the inferior nasal turbinate mucosa, accompanied by a slight rightward deviation of the nasal septum. **Interpretation of Findings:** * The presence of demyelinating lesions with a nonspecific, chronic appearance warrants further correlation with clinical symptoms and laboratory tests. * There are only minimal changes indicative of rhinitis. I find myself in a state of worry—should I be concerned? The idea of multiple sclerosis crosses my mind at times. Occasionally, I experience a bit of numbness in my left arm, though it might simply be attributed to my posture while working.
Experiencing Brown and Bloody Mucus in Stool Following Anal Exploration
I’m a 22-year-old male, standing at 5’9. Earlier today, I engaged in some personal exploration for about three to four hours. At first, I noticed a small amount of blood on the toy I was using, but nothing alarming, so I wrapped things up and cleaned up thoroughly. Throughout the experience, I felt no discomfort whatsoever. However, just now when I used the restroom, I noticed a slight mixture of mucus and blood in my stool, alongside a brownish tint at the end with only a tiny amount of blood. Fortunately, this was not accompanied by any pain or significant bleeding. The blood appeared to be a dull red rather than a vivid scarlet, and my stool was brown, not black in hue. Given these circumstances, should I consult a physician, or would it be wiser to take a break from anal activities for the time being?
