Question
I have pain in right shoulder blade when I lay on my shoulder blade in bed or sit on a couch and put pressure on the area. The pain sometimes radiates to the right collarbone area or to the bicep area or the lower arm. Mobility is limited somewhat. Sometimes the shoulder pops when moving it. Thank you for any help!

Answer
Have you injured the shoulder or played sports?  It can be a number of things ranging from a simple strain to a tear in the rotator cuff.  You may want to have it evaluated by a good chiropractor.  If you should have something more serious, they should be able to refer you to the proper physician.
