My little and adjacent fingers have gone from tingling last week to now being painful. what is wrong, what can i do?

Ulnar nerve: It sounds like you may have a problem with your ulnar nerve. This nerve can get impinged if you are putting too much pressure not eh nerve - this usually happens by putting to much pressure on elbow. You can stop resting your elbow on arm rests and get an elbow pad on. I think you need to get in and get a full evaluated and check your nerve function. Good Luck
