When I move after being in a certain position, I have a pain that occurs in the upper part of my chest. I wanted to know if this could be related to a heart problem?

The pain in the upper chest that you are experiencing when you move is unlikely to be related to a heart problem. It is more likely to be musculoskeletal in nature, possibly involving the chest area. To address the issue, it would be best to see a physiotherapist who can perform manipulations, such as in the sternum, to help alleviate the pain.
