I am 35 years old and recently noticed a nodular-type lump in my my right armpit area. It is somewhat painful to touch and also in the area surrounding it. It has not changed in size over the past 3 days, nor have I found any other nodules/lumps in the general area. I have not been sick lately, nor on any medications. Could this be a serious problem, and would you recommend that I see my general practioner or an OBGYN?
Thank you for your time.
