I have been experiencing sore breast for the last year recently they have become swollen and more tender. I had my tubes tied in 2010, I don t take in a lot of caffeine or salt, haven t had any weight gain in 6 months. Stress has been at an all time low for us lately. I exercise frequently, and wear supportive bras, still not understanding why breast are bigger and sore sometimes with itchy nipples no discharge, soreness goes into armpits and doesn t go away with menstrual cycle. Is this something I should be concerned with?
