I was wondering if nipple pain is a cause of concern? It is on the rt breast and is painful to touch. Nipple is red with some swelling. Also, I have some swelling in breast just below nipple and side. Went to my GP and she prescribed antibiotic and did a CBE (no lumps felt). She feels it's just an infection. I have no family hx of BC, I'm 35 years old, my first child was born at 29 years old, and my first period was at 12 years old. The pain feels like I've been pinched. All of this has occurred in the past three days (Tues, Wed., Thur.) went to GP on Fri(6/22). I was on my period this week. Never experienced anything like this before - could this be the beginning of hormonal changes?
