Whats wrong with my shoulder?!

Best Answer - Chosen by Voters

It sounds like you may have damage to your rotator cuff. It is probably tendonitis in the rotator cuff which would cause the clicking and pain in your shoulder. You need to see an orthopedist. Also after an injury it is not uncommon for osteoarthritis to set up in your injured shoulder and this will limit the range of motion in your arm and is painful. Here is a link that may help.

Try putting an ice pack on your shoulder and try to limit movements over your head as this will increase the swelling and pain.
I would go see a good Orthopedist. He may be able to inject some hydrocortisone into the area and this will relieve you symptoms and take away some of the pain and swelling. I hope this helps.

You are heading towards symptoms of Frozen Shoulder.

Please see an Orthopedic immediately.

In the meantime, never bathe in cold water.
Start exercises - free hand at once.
Stand in front of a wall.
Raise your hand slowly and lift it above your shoulder just as if you are writing on a School's Black Board.
Do not lift anything heavy
Do not pull anything heavy
Do not wash clothes for a few days

Try this 4 times daily from today onwards.
