Uthervers, I'm no expert, not a doctor, and I don't have HIV, not without officially being diagnosed yet. With that said and out of the way, I have been completely obsessed and reading everything I can on the matter within the past 51 days, and I've spoken to 3 doctors since. I've learned a lot, and I'd like to try and calm your fears. ARS has been researched to develop in recent HIV cases 10-28 days. Or 2-4 weeks. You're saying you didn't start feeling ill until 5 weeks which doesn't fall within the timeline. Secondly, if a person develops a fever through ARS it is generally above 100 degrees or more. Your fever could have been related to a stomach bug, or common virus you caught on the plane. People get sick all the time when they travel, especially during this wintery season. Your lymph nodes can be palpable, or felt. This shouldn't be alarming. When lymph nodes become a problem is when they are enlarged in different locations. You can't diagnose if your lymph node is enlarged. You probably have never felt your lymph nodes prior to this, either. A certified/qualified doctor or physician should be the only one's examining your lymph nodes. Just because you can feel it, doesn't mean something is wrong.
One last thing to add, ARS comes all at once. Not a symptom here, and a symptom there. I hope this helps. Like I said, I'm nobody special, just a concerned person like yourself.
