Hi I am a healthy (at least as far as I can tell) 24 year old man. I do suffer from mild sinusitis.
About 4 months ago I a lymph node in my right armpit swelled up, this lasted for about 2 days, as it was fading a lymph node in my left armpit swelled up.
I went to see my GP and had a range of blood tests done, including an HIV test. Everything came back saying I am right as rain.
Since then the cycle has repeated itself 4 times. Always one armpit then the other, sometimes spaced by a few days, and never remaining swollen for longer than 2 days. After the second occurrence I had some of the tests repeated but everything is seemingly ok.
This is now the fifth occurrence, a lymph node in my right armpit swelled up about 6 days ago and was back to normal 4 days ago. A lymph node in my left armpit became swollen today, the onset is fairly fast, about 3 hours from normal to as swollen as it gets, I expect it will be mostly gone by tomorrow evening.
A lot of things can cause swollen lymph nodes, including sinusitis, however I have had sinus symptoms a lot longer than I have had these swollen lymph nodes.
Any advice or suggestions are most appreciated.
