Some cases diagnosed as carpal tunnel are actually problems in the shoulder. Note, I said some, so don't take it that carpal tunnel is fake. It really is a problem for some as you see above. I know a woman that had carpal tunnel surgery on one wrist 3 times and even with trying to avoid tasks that would irritate or increase the risk of its return, it still kept coming back. She was finally referred to an assessment clinic where they look at all the possibilities. Her problems all originated in her shoulder and propagated down her arm. I don't recall the treatment she had, but think it was physio for the most part because I don't remember her having another surgery. Anyhow, it's no longer a problem for her. To bad our doctors aren't all perfect! Would help with so many of our complaints!
