On a serious note - when possible... avoid keeping your elbow bent tight and leaning on elbows. I have had problems with that nerve in both arms for years. Left was worse. Had it checked and they said not bad enough for surgery. Has gotten much better, but still some numbness and tingling in those fingers at times. Biggest things that helped me is keeping arms somewhat straight when sleeping and keeping keyboard away from me so arms are not bent so much. I think that is where most of mine came from.
