Anyone who is suffering this is probably looking for a magic potion to get rid of the agonizing relentless pain!. I have found something that works amazingly well for me so I thought I would share it. Chinese wood lock oil, wong to yick brand. Got mine on ebay after it was recommended to me and within a few minutes of rubbing a few drops into the shoulder it relieved probably 80% of the pain, fantastic.
It does smell and you need to put it on several times a day, but its well worth it.
If you are as desperate as I was, please give it a try.
