Lovely,
I have a friend who, around her cycle each month, has enlarged lymph nodes in her armpit...She also has fibrocystic disease of the breast (A benign, but uncomfortable condition), although I don't think it's related to that. I always thought that enlarged nodes were due to infection, (if they're painful) and can be from other things like cancer, in which case, are usually not painful.. But, I've also read that other conditions like CFS and FM can also cause it. Go figure!!
