Weird ANS saying that he chipped his elbow at a gig because I did the same thing about three years ago and I don't know how.
I was in Spain staying with a mate at his villa and we went out on the lash .. woke up the next morning with a rapidly yellowing elbow that was inflamed and very, very painful.
Once the swelling went down a week or so later, I could feel some bits of bone floating in there, where - like ANS - they remain to this day ..
It's like bits of gristle in a pig
Oh, and for everyone else : CHECK YOUTUBE FOR EXERCISES !!
As much as the rubber physio fetishist, performing exercises at home can help alleviate the pain quicker.
It still takes ages, but after a couple of weeks you will begin to feel a difference.
Example : for frozen shoulder, the two that helped most were walking my arm up a wall, using the fingers as "feet". The movement is still restricted but lifting it against a resistance surface helps.
Another one was standing sideways against a wall with your arm at a right angle so your hand and forearm are directly in front of you - like a Subbuteo "standing" goalie
Then you turn slowly away from the wall but leave the arm there, pressing the hand slightly against it.
It's absolute bloody agony in the shoulder joint, but do it ten or twenty times a day and you can feel it begin to ease slightly over time.
It's a marathon though, so know you're in it for the long haul ..
