<s>[INST] Hello, my name is Andrew. I m 18 and I recently noticed a rash on my shoulder that is near my armpit area. It is just beside the beginning of my bust and it is red and looks kinda like a cigarette burn. I also noticed some dry skin patches that don t hurt and aren t too noticeable that are almost symmetrical with the first rash. These aren t red or burn-like. I ve had dry skin pretty much my whole life due to the dry climate (Las Vegas) . I am afraid that it could be something bad. I had a blood and urine test in August and was told I was completely healthy. I m sexually active, but haven t had sex in a few weeks and plan being away from sex for awhile. Again, these just recently showed up. I don t know if its from dirt, sweat, allergies or even a possible HIV , but I need help because I m terrified. I don t think it s HIV because I haven t had any other symptoms of it besides a rash. Also I read on a blog that this woman had the same exact thing as I have described and she said that she found out she was allergic to wheat. So if you can help me that would be greatly appreciated. Thank you. [/INST] Hi I think you have a fungal infection of the skin which you might have contracted from your female partner who had the similar patches. It is called Tenia corporis and can be easily treated by using local clotrimazole cream and may require oral anti-fungal medicines too. Better consult a dermatologist who'll surely help you. </s>
