Hey I think I might have lymphomas. At first I was thinking it could be hiv because I had unprotected sex but I got test negative with 4th generation test at 7 and a half weeks(people says it's conclusive but not so sure). My symptoms I'm having right now that I makes me think that I have it is I have white tongue, my collarbone is showing more than usual (weight loss), and I think I get like a mild fever that comes and goes I get hot really easy and it's feels like fever but as soon as I take the covers off, it goes away. I also get itch but no indication of rash but sometimes it shows up like a bug bite and goes away in an hour or so. My neck pretty stiff too. I also have a irritation around my butt crack and sometimes itches and a strange odor. Do you think that I could have lymphomas? How can I find out if I do or not? I also been stressing out a lot because I thought I could have hiv so haven't slept well for couple days.
