You wouldn't, injuries are listed but aches and pains are never covered.

Scar tissue isn't the only issue that can make shoulders troublesome. I have tendonitis in both rotator cuffs and the slightest inflammation causes impingement and will prevent you from getting much sleep until it subsides, especially if you are not a back sleeper. Its a dull constant ache that has nothing to clean out or repair, if you lift your arm too high the dull pain can be sharp.

I found two things greatly effected my tendonitis, pressure changes due to weather and flying because of the pressure changes involved there. In my 5 years of traveling back and forth to Africa, I generally ate 12-16 ibuprofen a day.
