I am having pain in side of breast up near armpit from 2 days. I realised that I have purchased new bra and wore it daily for 4 days and it's tight. Now I have left the bra aside and not using it. Can the pain be from the bra digging into my skin. The soreness is only on one side on right and that's my dominant side. Pls reply respected dr I'm very scared no other symptoms no lumps or discharges. I visited gynac for checkup after being paranoid. Could this be the reason pls suggest me something .
