A scar isn't just a superficial injury. It cuts through connective tissue which must be checked when it heals. Scar tissue can damage the function of the body not just at the site but in other places on the body. Scars which are a result of some traumatic incident may also need attention in order to release emotional stress. If you have a scar due to operation or accident, please consider having it looked at. It can improve in texture and appearance and pain and discomfort can be resolved very quickly.
