<s>[INST] Four weeks after possible exposure I had swollen lymph nodes in neck for a few days. Then a couple weeks later I had muscle aches and headache which has lasted a week. I was tested five weeks after possible exposure and I was negative. I have also noticed some easy bruising. I also have these really small red dots on my body but not many. I had my doctor look and he didn t think it was anything. I never had a fever, sore throat, rash, and never had diarrhea or vomiting. Is a negative test at 5 weeks a good indicator of remaining negative? Also is easy bruising a symptom of HIV? [/INST] Hello, I can understand your concern. People infected with HIV develop antibodies against HIV in their bodies as early as 1 week after exposure and as late as 3 months after exposure. As you have got negative HIV test 5 weeks after exposure, I would advise you to repeat the test after 7 more weeks, that is around 3 months after possible exposure. If that test is negative, then 97% chances are that you are HIV negative, which is the best percentage any test can give. If the test comes negative, and you still suffer from swollen lymph nodes, easy bruising, headache and muscle ache, then you should go for blood test to determine complete blood count which will point towards what is going wrong, like presence of infection in body, possible allergic reaction, virus infection, platelet problems etc. Based on the test reports, further treatment can be advised. I hope this information helps you. Thank you for choosing Chat Doctor. I wish you feel better. Best, </s>
