The main symptoms include:1
- A dull ache in your hand, wrist or arm
- Tingling, pins and needles, or numbness in your hand
- A weak or clumsy hand
- Dry skin, swelling or color changes in your fingers and hand.
If carpal tunnel syndrome affects both of your hands, your dominant hand (the right one if you are right-handed) is usually affected first and more severely. Some people can't feel whether things are hot or cold. If the nerve damage becomes severe, you may lose the feeling in your hand. You might not be able to use that hand much any more.
Your doctor will need to examine your wrist and hand to find out if you have carpal tunnel syndrome. Tapping or putting pressure on the nerve at your wrist might make your fingers tingle (this is called Tinel's sign).1 Pressing the backs of your hands together and pointing your fingers down for a minute may cause tingling or numbness in your fingers (Phalen's test).
Your doctor may also recommend some other tests that measure the electrical activity of your nerves and muscles to confirm if you have carpal tunnel syndrome and, if so, how bad it is.2 These tests will show how severe the damage to your median nerve is. Your treatment will depend on whether your condition is mild, moderate or severe.
