Hello,
I'd like to suggest you read on both our RSD forum -
http://neurotalk.psychcentral.com/forum21.html
and our Thoracic Outlet Syndrome {TOS} we also have a RSI sub forum on the TOS section.
http://neurotalk.psychcentral.com/forum24.html
(
both wrists have tenosynovitis and Tendonitis )- might be due to RSI or even TOS.
Be sure to check the sticky threads on both forums too. They are up at the top section of the thread list.
