Well first i apologize for my english level. The situation is that i had unprotected oral sex with a prostitute on January. A week later or two i had a strange and oval red/Pink spot on my underarm, with the time it was more clear on the center. I went to the dermatologist and he said it was an eczema, ok, he gave me a cream and in some days it was so tiny that i couldnt even see it. Between july and december i´ve made many std tests because i was so worried and i was discovering symptoms, touching my body, i have a ocd and im with antidepressants. It came all negative except herpes-1 but i dont know if its new or i have it since a child.
Yesterday i noticed that the spot it was again there, but now, its more clear, here is a photo: http://tinypic.com/r/wteg5f/6 you can see now that its not so colorous. But searching the internet i´ve found patients with hiv with similar spots and it says that it has to do with a fungus that affects the people with this disease. Obviously i was tested for hiv and i was negative more than 1 time. It doesnt itch.
And as i said when it appeared it was smaller than now and the colour was a darker pink than now and and had well-marked form of circle, always whiter in the center.
similar than this photos that were those which panic me: http://www.gefor.4t.com/hongos/dermatofitos.html
