1summer,
hiv symptoms are notoriously elusive. In many cases, there are no symptoms until many years afterwards.
However, after initial ars symptoms, it is possible to identify certain symptoms attributable to hiv.
The virus itself harbours itself within the brain, lymph system and other organs, where it mutates. This means that the body's immune system must keep forming a new defense against it (which eventually leads to the break down of the immune system). Occassionally, this means that the lymph nodes will swell for a time. That is one symptom.
Another is drenching night sweats.
But these symptoms usually occur later on in the disease, and most of the time, could not be identified.
When a person is on medication, the drugs themselves can cause similar symptoms which are troublesome in themselves, such as the night sweats, headaches, nausea etc.
Now, I hope you are not speculating on any symptoms you might have, because as i've said many times before, hiv can never, ever be diagnosed by symptoms. Only a test three months after exposure can do that.
1summer, i've been rereading your previous post. Your risk was extremely low from what you describe. It would not be classified as unprotected sex. But more importantly, you did have a test after the definitive time of three months and it was negative. You are negative. I will repeat. You. Are. Hiv. Negative.
Finally, initial symptoms can last around two weeks. On average, someone who becomes infected may experience ars symptoms 22 days after exposure. This means they are seroconverting to hiv status, and a test will confirm this. We wait 3 months for definitive tests because that is the longest possible time researched for someone to seroconvert; but much more often than not, a person will seroconvert about 3 weeks after exposure and test positive after that.
