Immediately upon injury, use RICE (rest, ice, compression and elevation). Apply ice for at least the first 24 hours. Tape can be used for compression. Do not use the hand more than necessary. For severe injuries, your doctor may prescribe a splint or cast.

To help prevent carpal tunnel syndrome, watch your posture and your movements and make the necessary adjustments. Your posture is important when sitting at a desk for prolonged periods. Keep your wrists straight and your fingers dangling down. Your upper and lower arms should be at right angles, as should your upper and lower legs. Your feet should be flat on the floor, your back slightly arched, and your neck straight. Take regular breaks. When you rest, do some stretching, particularly your shoulders, arms and hands. Take time to massage your hands and wrists with lotion several times a day. The massage improves circulation and breaks up adhesions. An option is to wear supports or braces on your wrists to enforce correct positioning. Occasionally, drop your hands to your sides and shake them gently. This will stimulate circulation and reduce tension.

For CTS, wrist splints are helpful at forcing the join to be straight. Heat may relieve pain in the wrist, while cold may reduce inflammation. Try both to see which relieves your symptoms most effectively.

For any serious injury, consult your doctor.
