Hi, I am a 20 year old female who has been experiencing a mild sharp pain above my left breast. It began a week ago, shortly after spending an extensive amount of time sing. I assumed I might've pinched a nerve since I was singing a little over my natural vocal range, but it has just been getting worse. When a take a large breath sometimes he pain is heightened slightly. I was doing intense note taking today and after about an hour, the pain became much worse (I am left handed.) I am 5'5", 146 lbs, and my diet is relatively healthy, though I do have a bit of anxiety that is not medicated. My mother has asthma while my father has AFib and diabetes.
