Ask a Doctor and Get an Answer to Your Medical Question ASAP
I understand you are anxious as you think you may have contracted HIV? Your symptoms of fever/headache/swollen lymph nodes can be associated with many conditions including simple acute viral illnesses like the flu. I would recommend you to attend your local STI clinic. It is a walk in service and you can complete a full STI screen including screening for HIV.
Wish you all the best.
