I am 23years old man. I have swollen lymph nodes in my neck and my armpit for around 1 year and a half. And now, I start developing black spot on my legs and my tongue is always white with a few red spots at the edge of the tongue. My last exposure to a woman was in 25th January 2010 and I used to take HIV test twice since that time too. the first one was in 14th June 2010 and the result was "negative" and another one was in 20th July 2010 abd the result was also "negative". What chance can I have HIV? I really scare to go to take the test again. Are there any diseases can cause this symptoms? Oh, nowadays I always feel unwell when I sleep (both noon and night) but no night-sweat. Please tell me what I should do.
