Inflammation or small tears in a tendon (tendinopathy) can cause wrist pain. Although tendinopathy is a different condition than carpal tunnel syndrome, both can respond to the same home treatment tips:
Gently warm up your wrists and fingers before beginning an activity. Fan open your fingers. Stretch your wrists forward and back. Do some wrist circles. Repeat these stretches periodically throughout the day.
Keep your wrists straight rather than bending them while riding a bike, knitting, chopping, using a mouse or keyboard, using various tools, and driving.
Take frequent breaks from activities that require repetitive wrist and finger motions.
