Hello I am a 43 year old female, I am having, and have been for several weeks now, the pain comes and goes daily sometimes several times a day others just a few time. The pain is sharp stabbing pain under my left breast, radiating toward my left side under my arm pit...not in it. Then towards my breast bone. Does NOT hurt worse when I breathe. unless of course its a deep breath. I have had breast augmentation done 14 yrs ago, but I have NOT had any issues with them. I am concerned about the pain. Thank you for your time.
