Is anyone else having pain in their wrists???

My right one is especially painful. I'm wearing a wrist brace that the chemist recommended. Its helping at night to keep my wrist still but its not making a great deal of difference during the day. I was trying to move my thumb yesterday to stretch the muscles out but each time I did I felt a painful clicking on the inner side of my wrist (pretty much on the bone).

I've been told that this is fairly common in pregancy due to swelling of blood vessels etc but was wondering if anyone had any tips for reducing the discomfort and pain
