Hi, Anne. Jan is right on with her reply that rheumatoid arthritis can be caused by TMS anxiety and stress. It's all part of the back pain syndrome as far as I'm concerned. Pain is pain. If you, like I, am somewhat comforted by the "misery loves company" idea, you may feel better by knowing a report says there are about 40 million adult Americans suffering from anxiety, about one in four people, including many famous people such as Woody Allen, Johnny Depp, Barbra Streisand, Burt Reynolds, Cher, and Kim Basinger the actress who had it so bad it developed into agoraphobia. And many other famous people. Jan's suggestion was excellent, to look at TMSWiki entries on rheumatoid arthritis. They also confirm it is TMS-caused. Hope you can encourage your friend with RA to join TMSSWiki.org and get help from us.
