The : The symptoms you are describing are an indication of possible compression or injury to the ulnar nerve. This nerve starts in the spinal cord and ends in your small finger. Because of the distance this nerve travels, it can be compressed at several different points. One common site is on the inner part of the elbow at a point called the cubital tunnel. When you bump this area and feel a shock, the common saying is that we hit our "funny bone." another point of compression is at the wrist in what is called the guyon canal. A hand specialist can help you figure this out. You should seek professional help immediately. The longer your nerve is compresed the higher the chance of permanent nerve damage. Early intervention can prevent long term disability.

Ulnar neuropathy: This could very well be ulnar neuropathy of the elbow, which often gets triggered at night when the elbow is kept in the flexed position. An elbow sleeve, to keep the elbow relatively slight in your sleep, can take the pressure off of the nerve.
