I am 41 years old with 3 children. For my past 4-5 cycles, I have had a painful spot in my left armpit. It seems to start at about the time that I ovulate, and it gets progressively more painful until the day I get my period. At that point it seems to go away until I ovulate again. It seems to coincide with when I have tender breasts.
I was able to see an OB/GYN this morning while it was still inflamed but going down (period started last night). She said there is a lump in the spot I described, but she could find no other masses on either breast. I think she said the lump was 1-2 cm at the time. I am scheduled for a diagnostic mammogram and ultrasound this Friday. She seemed to think it is something hormonal, but I can't help but worry that it may be more serious.
Has anyone had experience with an armpit lump that painful premenstrually?
