Can a breast lump be the result of a pulled or torn muscle? I work out with exercise machines almost every day. I worked out a little more rigorously than usual a few days ago. The last couple of days I ve felt a tenderness in my left breast and last night i found a pea-sized lump about 4 inches above the nipple. Could this be caused by a pulled muscle or torn muscle tissue? I am a 47 year old female that has never had any major medical issues in the past.
