I am just recovering from the flu. Have had sever coughing for a little over a week. (Non-smoker). Now I have developed
extreme pain under my left breast when I cough or breath deeply. I also have pain under my left shoulder blade that feels
like a tense sore muscle.
Breast tissue is not sore to the touch, no lumps or bumps. Under left arm is not sore to touch.
Could I have pulled a muscle due to the sever coughing over the last week?
