Massage can speed up soft tissue injuries by increasing circulation to the injured area.  Pain relief occurs because this increased circulation that massage provides will decrease swelling and inflammation of your soft tissue injury.  The massage brings about  the breakup and release of waste by-products from the affected area and improved blood flow back to the area.  It will also loosen permanently tight muscles and strengthen lax muscles.
If you or someone you know is struggling with a soft tissue injury, know that massage can help.
