You might wanna have a PT or OT or doc check your hand. Could be the tunnel of Guyon and squishing of the ulnar nerve there, or it could be the ulnar nerve is getting squished at the elbow. The other wacky thing is that it could be referred from the shoulder or neck! I'm sure in your internet search you've found discussion of "Tinel's sign" at the elbow, and tenderness at the tunnel of Guyon, but bear in mind that these spots sing out to pressure even without pathology, so don't use them for your diagnosis.
Specialized makes a glove (about $18) that has a pad over the tunnel of Guyon. I'm planning to buy a pair as soon as I get my paycheck. They're nice.
