:wave: Can anyone relate to this?? I am a 54 year old female. I had a heart attack last year due to high colerestal which is now under control. I take atenolol and loads of vitamins daily. My problem is, my left breast is slightly swollen and in the area under my arm where the bra goes is swollen also compared to the right side.I can feel the differece when I put my arms down by my side. I can feel the swelling on the left. Also the left side in that area is tender. What could this be?? Once in awhile I will also get pains in the upper left arm. Is this a breast problem??
