Cubital tunnel syndrome: Hand numbness and tingling is not always carpal tunnel syndrome.
I have a funny tingling in my small and ring fingers while holding my cell phone to my ear or while holding a book when reading in bed. Why?
That “funny” sensation could be compression of the ulnar nerve at the elbow. The path of the ulnar nerve runs just behind the boney part on the inside of the elbow. The nerve is close to the skin and runs through a boney ridge without any substantial padding. The nerve must slide and stretch through this cubital tunnel with elbow movement.
Wait a minute! What does the nerve at my elbow have to do with the funny sensations in my hand?
Good question! The job of the ulnar nerve is to facilitate communication from your brain to your hand. This communication operates the muscles that help you perform coordinated movements with your fingers. Another job of the ulnar nerve is to take information about sensation at the ring and small fingers back to the brain. If the nerve is compressed or irritated, it can’t do its job. This condition leads to difficulty manipulating objects with your hand, feelings of weakness and sensations of tingling, numbness, burning or tightness in your fingers.
That doesn’t sound good. What can I do?
There is good news. There are some things you can try that might calm the nerve. Nerves do not like to be crowded. The ulnar nerve becomes crowded at the elbow with direct pressure over its path or when the elbow is held in a bent position for an extended period of time.
Here are a few tips:
