I have pain on my right side shoulder. at times it becomes difficult to raise my hand. would you kindly tell me whst it is and the medication. thank y?

Rotator cuff: Start with some easy exercises to work the muscles of the shoulder blade that the rotator cuff attaches to. This will take some of the strain off the cuff. Use a rag and wipe a surface in the numbers of a clock face from the center up to 12:00 then back to center then 1:00 and so on. Start on a flat table top and gradually work your way up to a mirror or other vertical surface. Motrin may help.
