See the doc.
I have it right now.. right shoulder.. limited movement and lots of pain.
There are a couple of tests that can help..
1) Can you bring the affected arm (and hand) behind your back.. and touch between your shoulder blades (the bra test..) It should be easy and pain free.. if not then something is limiting movement. Adhesive encapsulates is idiopathic (no obvious cause) although can be related to injury/ over use.
2) The x-ray or ultra sound should show a 'clean shoulder'.. i no torn rotator cuff etc, no damage. yet it hurts like hell and you cannot move it.
I have had two hyrodilations ( injections .. 10cc..of long term painkillers and weak steroids) in mine since last August.. Getting much better and movement is far far easier. Another few months should see me clear of it.
There is a simple surgical procedure that clears it faster.. however not keen on inessential knife work...
I found the best physio for me was breast stroke..... an hour or so every day....
