Can anyone help me with my tennis elbow problem?

I have a pain in my elbow, I’m pretty sure it’s a condition called tennis elbow. I saw my doctor at my check-up and told him about it. He asked if I was icing it and I said "yes." He didn’t really say anything else about it. I had this problem twice in the past but it didn’t last long both times. This time it seems like it’s here to stay. Does anyone know any exercises or anything that will help it heal without me decreasing my physical activity? I’ve already looked in Wikipedia and read over that page. Thanks a lot.
