Hello - I may possibly have a STD. I m male, 59, heterosexual, teach at a college, have not been sexually active for 2+ years, and have twice been tested for herpes and HIV – both negative. Vegetarian/vegan for almost 40 years, low BMI, very fit, never a smoker. At least annual visits to Panama & Brazil (2008-2014); combined 8 months in Ecuador and Colombia (mostly Colombia) in 2015. (The symptoms I describe below may occur less frequently when I’m away from my home in upstate NY – doubt it’s Zika, etc.) My symptoms are: intermittent rashes (red, non-itchy, non-painful but slightly sore, patches on the glans and inside of the foreskin of my penis; no discharge), often weeks apart, but sometimes more frequent. The patches have persisted unusually for about 2 weeks now, on and off. Although I have had small ulcers in these locations in the past – these rashes are different (or perhaps smaller, coalesced, ulcers). I have had both these red rashes and small ulcers going back to my 20s, but only very infrequently (again – testing negative for herpes twice – once in my twenties from a urethral swab and recently from a blood test). Over the last few years these symptoms have become more frequent, and are associated with feeling a little run down (mild headaches, very mild cold-like symptoms – isolated sneezing and coughing – but very mild). I’ve also noticed that my flaccid state is smaller when these symptoms are present. In the last 4 years I’ve twice had a full blood workup with nothing showing except transitory low Vitamin D and B12 (short term high dosages prescribed; multivitamin taken for 5+ years). (List of tests below.) My GP and a specialist both thought my symptoms were not of an STD and suggested the periodic malaise could be a symptom of mild depression. But neither seem to have an explanation for the very specific STD-like symptoms - other than they might be a symptom of mild depression. (The doctor for my annual skin-check last week didn t think this was likely and suggested additional STD testing.) I’d very much appreciate any additional thoughts. Thanks.
