Questioning My Hidradenitis Suppurativa Diagnosis – Could It Be Something Else? (37M)
I'm a 37-year-old male, standing at 5'11" and weighing 245 lbs. Although I fall into the overweight category, I don’t smoke. My concern centers on the sensitive area at the underside of my thighs where they meet my scrotum (I’ve obscured that part for discretion, but there’s also some mild irritation on the back of it, appearing reddish without any bumps). For the past six weeks, I've been dealing with this skin irritation or rash. I attribute it to an incident where I became overly engrossed in completing a project, accidentally resting a hot laptop on my lap for over three hours without any protective barrier. Due to my tendency to sweat a lot, I didn’t realize how hot and sweaty I was until it became a problem. The discomfort worsens when I sit down or if any fabric comes into contact with the area. I consulted my doctor, who was initially uncertain about the diagnosis and opted to prescribe a steroid cream mixed with an anti-fungal treatment as a precaution. Unfortunately, this remedy was ineffective. Prior to my appointment, I had tried some over-the-counter solutions like hydrocortisone cream and jock itch treatment. Following that visit, my doctor referred me to a dermatologist. Yesterday, I finally had my appointment with the dermatologist. After briefly reviewing some photographs taken by a physician’s assistant and examining my condition for less than a minute, he described it as “pimply” and proposed treating it as hidradenitis suppurativa. He prescribed clindamycin cream for daily use over a month, along with doxycycline 100 mg to be taken twice a day. However, I wonder if my condition could be something different, like erythrasma, given the appearance of patches and the wrinkled texture of my skin. I’ve not experienced any swelling beyond what was observed, and there has been no discharge or pus present. I would appreciate your thoughts on this matter! Thank you for your time and consideration!

It's understandable to feel uncertain about a diagnosis like hidradenitis suppurativa (HS), especially when treatment has not been effective so far. Your concerns about whether it could be something different, such as erythrasma, are valid. Both conditions can cause skin irritation in similar areas, but they have different treatments that can significantly impact your comfort and health.
Understanding Your Condition
- Hidradenitis Suppurativa (HS): This is a chronic skin condition that usually involves painful lumps or abscesses and can occur in areas where skin rubs together, like the thighs or groin.
- Erythrasma: This is a bacterial skin infection that often occurs in moist areas. It typically causes reddish-brown patches and may have a wrinkled appearance, but it tends to be less painful than HS.
Next Steps
Given your symptoms and treatment history, here are some prioritized steps to help you address your concerns:
-
Continue Current Treatment: Use the clindamycin cream and doxycycline as prescribed by the dermatologist. Stick to this regimen for at least a month to see if there is improvement, as HS can be resistant to treatment.
-
Monitor Symptoms: Keep a diary of your skin condition, noting any changes in symptoms. Pay attention to factors such as skin irritation, changes in color, and any irritation following certain activities (like sitting or sweating).
-
Skin Care Practices:
- Hygiene: Gently wash the area with mild soap and water, ensuring it's dry afterwards. Avoid using harsh soaps or scrubbing too hard.
- Moisture Management: Keep the area dry and cool to prevent further irritation. Consider wearing loose, breathable clothing to minimize friction.
- Use of Barrier Creams: If approved by your dermatologist, consider applying a barrier cream or ointment to reduce friction and protect the skin in that area.
-
Follow-up Appointment: Schedule a follow-up with your dermatologist in a month to reassess the situation. If your symptoms persist or worsen, express your concerns about the diagnosis and discuss the possibility of erythrasma or other conditions.
-
Explore Lifestyle Adjustments: Since you mentioned sweating, consider lifestyle changes that can help manage perspiration—like wearing moisture-wicking clothing and staying in cool environments.
Conclusion
You're on the right path with professional help, and it's crucial to give the current treatment a fair chance while carefully monitoring your condition. If you notice any significant changes or new symptoms arise, don’t hesitate to reach out to your healthcare provider sooner. Your comfort and health are the most important priorities.

Navigating Autoimmune Challenges: My Ongoing Health Struggles
At 28 years old, standing 5’3” and weighing 155 lbs, I don’t smoke, yet I am navigating some significant health issues. My diagnoses include Lupus and relapsing polychondritis, and over the past year, I have found myself repeatedly falling ill. The pattern is frustrating: I often start feeling unwell, and a visit to my rheumatologist results in a month-long prescription for prednisone. While the medication provides relief, the same illness returns as soon as I finish the treatment. I initially tested positive for Cytomegalovirus (CMV) and underwent antiviral treatment, which eventually yielded a negative result. Additionally, my bloodwork indicated a history of Epstein-Barr virus (EBV) and human parvovirus infections; however, these appear to be dormant now. Thankfully, my tuberculosis test came back negative. The symptoms I experience are debilitating and include: - Intense headaches - Severe fatigue that resembles the exhaustion felt after an intense workout, leaving me almost immobile the next day - Swelling in my joints - A scratchy or sore throat - Lack of fever - A general sense of malaise, akin to feeling flu-like, which confines me to bed for days. This situation has left me bewildered, especially since my lupus and relapsing polychondritis were previously managed adequately. I have undergone numerous laboratory tests, and while the results are extensive, some notable abnormalities include a DNA DS Antibody level of 73 (down from a staggering 6,317 two months prior) and a C3 complement level of 64. My complete blood count (CBC) with differential did not reveal any significant abnormalities.
Using THC While Taking Wellbutrin: Is It Safe?
Hello! I’m a 27-year-old woman, weighing around 150 pounds and standing at 5'3". I have no history of smoking and no other medical conditions. At present, I'm prescribed 25 mg of sertraline, and I've just begun treatment with 150 mg of Wellbutrin, both of which I take every morning at 5:30 am. I’m curious if I can safely consume THC while taking these medications. I sometimes enjoy THC gummies because they provide me with relaxation and amusement, in addition to aiding my sleep. Since starting Wellbutrin, however, I've noticed I'm waking up multiple times during the night—around five times last night, to be precise. Furthermore, I'm wondering if it would be safe to take Hydroxyzine as needed?
Foreign Object in Eye
I’m a 19-year-old female, weighing 43 kg and standing at 158 cm. I don’t wear glasses or contact lenses and am currently not taking any medication. Earlier today, I accidentally dropped my blanket and, when I shook it out, something got into my eye. I suspect it might be a crumb. I attempted to rinse my eye with water while in the shower, but it was quite painful and didn’t resolve the issue, so I stopped. At the moment, the discomfort is minimal unless I blink quickly, squint, or touch around my eye. My vision seems mostly unaffected, although occasionally it gets a bit blurry. I'm wondering if it's okay to just let it be for the day and even sleep it off. What should I do next? Tomorrow happens to be a public holiday, which means I can't visit a pharmacy, and I don’t have any eye drops on hand. Any advice would be appreciated!
31M, 164cm, 82kg - Concern About Long-Term Effects of Substance Use and Medical Dismissal
It has been a couple of months since I last used any substances. Currently, I am experiencing several troubling symptoms. When I’m sober, I observe that my right pupil is noticeably larger than the left, particularly in dim lighting. Additionally, I occasionally see flashes of light when I shift my gaze and suffer from persistent floaters and visual disturbances. Balance has become a challenge for me, and there’s a slight tremor in my right hand. Moreover, I often notice that my head and hands feel flush. My anisocoria fluctuates, making it harder to detect in brighter conditions. Furthermore, there’s a perennial slight pinkness in my left eye that suggests some form of inflammation. My eyelid on the same side also appears droopy. Throughout my life, I had never sought medical assistance, but when I finally did, I felt dismissed by healthcare professionals. They often brush off my concerns, possibly because of my young age and seemingly robust health. However, deep down, I sense that something is wrong. I have engaged in risky behaviors involving high doses of stimulants administered intravenously and survived, but I no longer feel like my normal self. It’s concerning that nobody seems to take my situation seriously. I am neither psychotic nor do I possess any background of anxiety disorders. My foremost concern revolves around the possibility of having a brain tumor, an aneurysm, or an arterial issue. Yet, whenever I advocate for imaging tests, I encounter resistance from the medical staff. All I wish for is reassurance that I am not facing immediate health threats or dying as a consequence of my past decisions. My goal is to attain optimal health without the fear of sudden collapse. I have compiled an exhaustive list of my symptoms and worries. Would it be beneficial to present this information to my general practitioner, or might they perceive me as merely paranoid? - Persistent daydreaming or zoning out - Visual disturbances including visual snow - Occasional light flashes in low light environments - Poor nighttime vision - A creaking sound in my neck or ear on the right side during substance use (now resolved) - Numbness and tingling around my right eye that intensifies when lying down - Anisocoria with a potentially dilated right pupil (uncertain if the left isn't dilating adequately) - Eyelid droop - Tremor in my right hand - Gradually worsening clumsiness - Difficulty with word retrieval and trouble performing simple mental arithmetic - Inconsistent diastolic blood pressure readings between arms (a difference of 10-14 mmHg) - Facial flushing; my entire face, palms, and chest turn bright red - Vasoconstriction in my extremities; red fingertips and pale fingers.
Persistent Swelling in Lymph Nodes for Over Two Months
Hello! I’m seeking some guidance. I’m a 30-year-old female who doesn’t smoke or drink. Since June, I’ve noticed a peculiar lump on my chin. Initially, I suspected it was a recurrence of a cyst that was surgically removed in 2002. However, a recent CT scan revealed three swollen lymph nodes in the submental area, with one being particularly prominent. The visibility is exacerbated by an existing scar in that location, making it more pronounced. After consulting two different ENT specialists, I have not found any relief. They prescribed antibiotics, yet the swelling persists. The size of the lymph nodes varies significantly; at times, they are quite large, while on other days, they shrink down but remain noticeable. It has become increasingly frustrating, and I feel self-conscious about my appearance in public. I began taking birth control (Junel 20/1) in May to manage my painful and heavy menstrual periods. Recently, I visited my OBGYN to investigate any possible connection between the medication and my symptoms, but she assured me that there is no link. Aside from the birth control, my diet and supplement intake remain unchanged. Recently, I’ve experienced intermittent bouts of nausea, which is uncommon for me, although no other symptoms have emerged. My blood tests and CT scans have all returned normal except for the swollen lymph nodes, and I was in good health before this situation arose. It's been over two months now, and I feel like I am at a dead end with no solutions in sight.
