I have had pain near my lymph nodes in my neck, but the one that has been most bothersome is my axillary lymph node (armpit), but just on my right side. To be honest, I don't really know if it is my lymph node that is hurting, or just a muscle or something else in that area. The pain in my armpit will come for a couple of days and they go for a couple days. Then, lately I've had pain in the area where the lymph nodes are in the groin area. This pain is new. I've not had this pain until just a few days ago. I just had my period...I think...I don't know if I really know when I'm having a period or when I'm just spotting since I've had this stupid Mirena. Anyway, the groin pain came with the start of the period, or spotting.
