What Could Cause Burning And Tingling Sensation In Hands Every Morning?

Hello - Most mornings for the last few weeks, I wake up very early to stiffness, tingling, and sometimes burning in my hands and lower arms. I ve tried sleeping in different positions, and on different surfaces. This does not happen every night, and it occasionally happens randomly during the day. I don t do a lot of typing, but I sometimes do a lot of physical labor (landscaping) with my hands. I ve tried wearing braces designed to lesson carpal tunnel syndrome. Still no relief. Please describe any possible causes and/or treatments. Thank you. XXXX
