A few years back I had a painful bout of Carpal Tunnel Syndrome. Several occupational therapy sessions plus using two types of gliding exercises the therapist provided helped to reduce pain and restore strength in my hand: the exercises are shown in the pictures below, along with instructions. The CTS gradually faded away as I used the exercises, kept my wrist straight at night by resting my hand and forearm on a pillow while sleeping, and shed quite a few pounds (I had given up smoking and become enormously fat afterwards).
