If you don’t get some kind of therapy and get those muscle fibers massaged and back in place, what’s going to happen is you won’t heal properly. The muscles won’t lay back down where they’re supposed to and you’re going to end up with scar tissue in there, and that scar tissue can be in there for the rest of your life. So even a sprain or strain can really be serious and can need treatment. Name any kind of traumatic injury — it can happen in an automobile accident.
