Carpal Tunnel Syndrome
What Is Carpal Tunnel Syndrome?
Carpal tunnel syndrome, also called median nerve compression, is a condition that causes numbness, tingling, or weakness in your hand.
It happens because of pressure on your median nerve, which runs the length of your arm, goes through a passage in your wrist called the carpal tunnel, and ends in your hand. The median controls the movement and feeling of your thumb and the movement of all your fingers except your pinky.
Carpal Tunnel Syndrome Causes
Often, people don’t know what brought on their carpal tunnel syndrome. It can be due to:
- Repetitive motions, like typing, or any wrist movements that you do over and over. This is especially true of things you do when your hands are lower than your wrists.
- Conditions like hypothyroidism, obesity, rheumatoid arthritis, and diabetes
Carpal Tunnel Syndrome Symptoms
Symptoms of carpal tunnel include:
- Burning, tingling, or itching numbness in your palm and thumb or your index and middle fingers
- Weakness in your hand and trouble holding things
- Shock-like feelings that move into your fingers
- Tingling that moves up into your arm
You might first notice that your fingers “fall asleep” and become numb at night. It usually happens because of how you hold your hand while you sleep.
