So I've been diagnosed with Musculoskeletal chest pain, and I've told my doctor I experienced a bit of trouble breathing but there are days where I can breathe normally after a bit of exercise. I was also wondering if that could be the reason for my heart feeling as if it were beating faster, for example I went bowling yesterday and my heart would feel like it was beating faster and I would have to rest after a few games of bowling. This usually doesn't happen (faster heartrate from doing small activities) to me. I was wondering if this would go away soon enough or if there are any treatments, I was told to use a heating pad and I guess that helps a bit. Thanks!
