How do I get rid of Tennis Elbow?

My elbow has been hurting for about a year now. My symptoms indicate tennis elbow, but I don’t play tennis. I do work on the computer daily. It is very bothersome and hurts to bend it or lift objects that are not that heavy. I bought a tennis elbow brace that sits right below my elbow but it doesn’t help much. How can I get rid of this? It hinders any exercising I want to do using arm movements.
