I've had it more than once. It can be a ligament issue or something docs call ulnar neuropathy, where the ulnar nerve in your arm gets trapped in the notch of your elbow. I speak as a patient; not as a doctor, so pardon if this definition is not completely accurate.

Anyway, I had physical therapy for it. It was primarily an exercise where you extend the affected arm out fully and then, using your other hand, pull your wrist back for a count of 10. Then do it again, bending your wrist forward. Do this a couple times a day -- and especially before you play.

Google "golf injuries" for further insight.
