HELP! Ive been getting the cysts without fail with my period for years. In March of last year I had surgery to remove it. We packed it for four or five weeks before it healed. Then, like clockwork with my menstrual cycle it came back. I am very clean, I Brazilian wax, I dont know what to do. I just had bilateral mastectomy and am supposed to return to work next week and of course it's back. Swollen and painful. Has anyone had any luck with treatment that actually stops it from coming back or helps resolve it quickly?
