Hi Laura,
Sorry you are also dealing w/ CTS... I have it, too, and it's very painful. Like Susie said....braces are a good thing and mornings are the worst. No, it's not just confined to the hands - it can run up the wrists/arms, etc. I just cortisone injections in my hands last week. You can only do this on a limited basis, but it does help give me some relief at times. I've chosen not to do the surgery for various reasons.
There's a simple test that "can" indicate carpal tunnel syndrome. I'm too tired to describe it... but it's called the "phalen's test" if you google it.
Take good care, Laura.... --Tina
