Hi, I am 29 years old. I have pms. And have been suffering from breast soreness pain through out the month more or less. Currently on episoft e without tight fitting bra hurts more. Have done sono mammography 2 times reports are okay. My question is how frequent we can do the sono mammography (breast ultrasound. I can not do chest exercise it hurts more. I was fat 2-3 years ago reduced weight is it the reason breast problem? Due to breast pain sometime I am very tensed.
