shoulder pain

[Bill]

I have this pain in my shoulder that sometimes extents half way down my upper arm, only when I reach back to grab something or at the very extent of my reach over my head, any ideas?

Bill----it sounds like "impingement", which is a rotator cuff inflammation. Typically a little Physical therapy will help! Check out this link for a couple of instructional videos etc:
