I was stabbed in the left chest about 2 months ago and since then I have been working out a lot more. My doctors said I was full released but I still feel a little pain. But I don't know if it is pain or just scar tissue. I was wondering on my left side my oblique muscle doesn't seem to contract like normal. So I want to make sure I can do heavy lifting and not have to worry? When I get done working out my left side and and upper chest is considerably more sore than my other side. I was curios if this was normal I am thinking it is but I flipping out about it because it is right around my heart. The stab wound was right below my left nipple and little down and toward the center. Please help if you have any information for me or any good sites with information. Thanks
