You have probably been the victim of an assault to your ulnar nerve, which can occur when you hit your “funny bone”. Normally, the sharp elbow pain, tingling, and numbness only last a few seconds, but with repeated irritation, this pain and subsequent damage can last for days. Your ulnar nerve covers a lot of real estate, traveling from the neck region of your spinal cord all the way down the forearm to your hand. It can become entrapped or pinched at numerous points besides the cubital tunnel of your elbow, though cubital tunnel syndrome happens to be one of the most common reasons for nerve entrapment neuropathy in your upper limb.
