Can anyone identify with my problem. I had polio as an infant which left me with little use of my left arm. Still have feeling in arm but only grip in 2/3 finger and a little wrist movement otherwise the muscles are wasted. I have experienced aches and pains in my left chest area for most of my adult life but recently these have become more prevalent and accompanied by fatigue. In general i would say its intercostal muscles and possible as a result of the inbalance in my upper body due to lack of upper body development on my left side ( arn/shoulder/and pecs)
If anyone has or is experiencing similar problems I would love to here of your experiences.
