Tennis (photographers?) Elbow

I've been getting severe sharp pains in my elbow. After doing some research found out it's called tennis elbow. Thought it was unusual, but found out after attending the Wedding & Portrait Photographers convention in Las Vegas that it is becoming a regular malady among photographers these days. Between lifting your camera up 400-500 times in a day, along with the flash and any other attachments and the position of your arm when working on the computer files it strains that ligament. It's pretty amazing that once you acquire something like this you find a whole pile of people who suffer from the same thing.
