Last year, I had surgery to take the pressure off a nerve on the inside edge of my right elbow. All my symptoms went away, but now I have a new one. Whenever I put any pressure on the inside of my elbow, I get a tingling sensation down my forearm into my little finger. Sometimes this happens just from pulling on a shirt when I get dressed. What is causing this?

Tingling sensation from tapping, bumping, or putting pressure on a nerve is called Tinel's sign. This may be a sign that the nerve is continuing to heal after surgery. It happens in about a quarter of all patients who have the surgery you describe. It can also be a sign that the nerve is permanently irritated or partially damaged. You can expect to see continued improvement for up to 18 months after this type of surgery.
