I keep getting a rash under my left armpit, even when i don't shave for a few days. I changed deodorants to one with melaluca and it burns. I have had breast issues with my left breast for a long time and am still waiting to get answers. I also keep getting small red rash dots in the same area lower under my left armpit, closer to my breast. I have had various mammos/ultrasounds done due to ongoing breast pain and a thickening feeling I have had in my left armpit/breast area and they cannot see anything on the mammogram. Could this be a beginning sign of IBC? My nipple also is VERY tender whenever I touch it. I do check it every morning for leakage just because I am VERY afraid of getting Breast Cancer since it runs in my family. Any advice?
