What Are The Symptoms Of HIV?

Hi Doc, This is a(n) HIV-related paranoia question. Last summer, I discovered my partner had cheated on me. We had continued unprotected sex before this came to my knowledge until about late July, early August. During the month of September, I began experiencing intestinal discomfort, enlarged lymph nodes (I had severe Mono about six years prior,) constant fatigue, fever and night sweats. I had about four tests spanning three months, all blood and all negative. However, since then, my lymph nodes have begun to randomly swell and shrink, I have a constant tongue coating (Doc confirmed it did not appear to be thrush,) which is usually yellow or white (but has once or twice been a sky blue.) The intestinal issue has my doctor thinking it is gastritis/GERD. However, for the past few weeks I developed dry, small, itchless, red patches on my right arm and left elbow. They are all about 1-2cm in length and not in clusters. My chest has inexplicable, also itchless, red bumps from shoulder to shoulder. I think I am going insane and this is the primary cause for all of these bizarre health issues. I cant shake the feeling that I ve contracted HIV when all tests have confirmed my negative status. Any feedback would be highly appreciated and overly valued. Thank you.
