Carpal tunnel syndrome is a condition in which the median nerve (the main nerve in the hand) becomes compressed at the level of the wrist. This nerve runs together with the finger flexor tendons through a narrow passage called the carpal tunnel. When pressure builds up in this tunnel, the nerve becomes irritated and symptoms can occur.

Cubital tunnel syndrome is a condition in which the ulnar nerve (the nerve at the elbow) becomes compressed, causing tingling or loss of sensation in the ring finger and little finger. Sometimes it helps to take rest, but if symptoms persist, surgery may be required.

De Quervain's syndrome is an inflammation or irritation of the tendons on the thumb side of the wrist. The tendons do not have enough space to move smoothly, which causes pain when gripping, twisting or lifting. The pain often worsens with rotational movements or when lifting a baby.
