Breast pain and horrible armpit odor. It smells rancid ...
(smells like pee). I only wear cotton now and once in awhile I get that smell, it can also be caused by dehydration. Hope this helps someone. MwaFor the last 4 or 5 years I have had breast pain and tenderness and lumps. I have about 20 or more lumps in each breast. I am only 22. I have also had a Rancid sour smell that comes from my armpits.
