Hand Pain

Carpal tunnel syndrome

What is carpal tunnel syndrome?

The carpal tunnel is a narrow passage in your wrist made up of small bones and a tough band of tissue. It acts as a pulley for the tendons that bend the fingers. Carpal tunnel syndrome (CTS) is a relatively common condition that causes pain, numbness and a tingling sensation in the hand and fingers due to irritation of the median nerve in this tunnel.

  • Pins & needles relieved by shaking your hands
  • Dull aching in your hands

How do I manage this problem?

  • Using wrist pads while using computer
  • Stretching the forearm muscles may also help improve your symptoms
  • Simple over the counter medications from your chemist to control the inflammation may reduce the symptoms
  • In pregnant women it usually improves on its own 3 months after giving birth

What treatments are available?
