Hi Thomas01, Some of the symptoms you have described are similar to that of HIV but this is not to say that you have been infected nor does it suggest that your symptoms are related solely to HIV infection. Discharge, mouth ulcers, fatigue, headaches, rashes, joint pain, mouth sores etc. are more commonly known to be associated to other STI's such as syphilis or herpes that generally affect the mouth. It is great that you have taken the initiative to test for HIV, after being sexually active with more than 1 partner, but I would recommend if you haven't already, to test for all sexually transmitted infections just to be sure. Depending on the time since exposure and the type of test performed, a negative HIV result is a very good indication. You mentioned that you visited a clinic on 27th of October of this year and received a negative result. If your last exposure/sexual contact was the 29th of September then that is nearly 1 month later and most tests performed at clinics are 4th generation tests and therefore have a window period of around 4 weeks. This means that if you have tested around 4 weeks, since your last exposure, then your negative HIV result can be relied upon greatly. I'm sorry that you feel like you cannot live thinking and worrying about this but your life is worth so much more than this. The fact of the matter is that HIV is now treatable. Given, there is not yet a cure, but if diagnosed early enough, someone living with HIV can now live a long, normal and relatively healthy life. Do not beat yourself up about this, everybody makes mistakes. You have done the right thing in testing. I would perhaps recommend speaking to your doctor or GP to ask about the symptoms you are experiencing and take any advice they offer. We are not medical professionals and are predominantly experienced in HIV testing so please speak to your doctor to find out more about STI testing.
