Hi, welder,
This could also be arthritis calcification, also known as a "spur". I am not a Doctor, but am a person who has been taking Glucosime-Chrondoitin capsuls for about 5 years now.
I had, notice the word "had", a calcification spur on my left shoulder. It really hurt. I could not even raise my arm over my head. The X-Ray should the spur.
The spur is now gone!
My wife went to a Gastroenterologist for a stomach problem, which he cured. He also told her to start using the same capsuls for the back of her neck. She had been on arthritis prescription medication for 4 years... not helping her that much. She has been using these Glocos capsuls now for a year, and is much, much better, with hardly any pain at all!
It would well be worth your time and a little money to buy a bottle of Glucosamine-Chondroitin capsuls.
I get them from:
http://www.americannutrition.com, about $23, including shipping, for 240 capsuls. Much cheaper than in our local drug stores.
Although your Doctor may not have mentioned "arthritis", calcium deposits are in the same neighborhood.
