I fell 2 months ago..my rt upper arm is in pain so that sometimes i have to use my other arm to lift ? what may be the problem

Rotator cuff tear: If u did not fracture your proximal humerus in the fall( thank goodness) and now have pain in your shoulder w/ motion away from your body or above your head than you may have torn your rotator cuff tendon(s).Pain@ night is typical. Weakness may be present.See an orthopedic surgeon who specializes in shoulder problems / arthroscopy.Best of Luck!

.Need exam: You need to be examined. You have either broken your shoulder or have ruptured or injured a muscle or tendon. Not all fractures show up on X-Ray early in an injury..
