If you donāt get some kind of therapy and get those muscle fibers massaged and back in place, whatās going to happen is you wonāt heal properly. The muscles wonāt lay back down where theyāre supposed to and youāre 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 ā it can happen in an automobile accident.
