about two years ago i injured my chest while doing push-ups. i thought it was just a pull, so i took some time off and waited for it to heal. i still have occasional pain in the sternum area on my right pec and the right pec muscle is now significantly smaller than the left pec. I am wondering if this disfigurement is permanent or if anyone else has had a similar issue. I've attached a picture, but it is kind of hard to see the deformity. the entire pec is smaller, and there's an indent in the upper right corner.
