I have two swollen lymph nodes on my right armpit. One is considerably big and the other is quite tiny. These started to hurt about 3 days ago and became visible only yesterday. I had the flu which I am still not fully recovered from and also got my menstruation today. Could this be the cause or shall I go and check it out? Thanks
