Contact sports and high impact sports often result in dislocations, which is when bones that form a joint become separated.
If a joint is dislocated, you will feel intense pain, and you may also experience nerve damage due to the dislocation.
After a dislocation, the joint will have to be put back into place.
Sometimes that is just as painful as the actual injury, and you might need to wear a sling or brace for several weeks until the swelling goes down.
Rehab is often recommended after dislocations, especially shoulder dislocations.
Rehab can restore the strength and range of motion of the injured joint.
