How Can Shoulder Pain Be Treated?

Hi, I m experiencing rt shoulder pain, x-rays show no bone issues. A round of prednisone did nothing. also have very stiff, painful neck in the traps, limits turning radius. Other areas of painful joints include, left knee, right hip, both wrists, both ankles off and on. Patches of skin, diameter is shape of large pear, that are Very sensitive to touch by anything. The patches are usually the inside of both forearms as well as patches on various areas on both legs. There is no red or flaking of the skin. Its present in the areas I ve mentioned at different times. Lastly, eyes become blurry without the presence of film on the eyes, but I see it in my vision. I have been diagnosed with RA. Not a hypocondriac......... Tony S.
