What is causing the tightness in my upper central chest?
I am a 44-year-old female who runs nine to 10 miles every other day in usually very humid weather. Recently I have noticed a tightness in my upper, center chest. It's tender when I push on it. It feels like the muscle soreness onset by hard upper body weight training. It doesn't stay sore for long; usually I can push on the area pain-free five to 10 minutes later. At times I feel out of breath running, which is new for me, but other than that I don't have any symptoms. The soreness doesn't only happen on days I run, and sometimes even seems to radiate into my upper back. There doesn't seem to be a discernible pattern of occurrence. What could be causing this?
