A swelled lymph node could be a symptom of dozens of any other things. It is not specific of HIV. I don't even know why you are so concerned about HIV, since you said you have always had protected sex.
thank you Joan. I know sometime people worry too much. But if you could answer my question could a single swelling lymph node be a sign of HIV?
