I have what appears to be a lump above my left breast. It's not quite my breast (and doesn't feel like it's breast tissue) or my armpit so I'm not sure if it's anything to bother about. It feels about the size of a small marble but is easily moveable and doesn't feel hard. I'm not sure if it's related to the muscle there although there isn't one on the other side. I have also had some green discharge from that breast but only under pressure. I am 43 but had a hysterectomy about 3 months ago and figured that may be related to menopause.
I know I should probably go and get it checked but I worry that they'll think I'm stupid if they can't feel anything.
