Tennis elbow is on the outside of the elbow knuckle and golfer's (aka thrower's) elbow is on the inside.
I've had some experience with golfer's elbow thanks to having a warehouse job years ago picking up 150 lb. monitors. It took years to get over it but it is possible. I thought I would have this tendinitis for life. I pretty much avoided exercises that caused me pain in that area and when it did hurt, I put ice on it.
I am pain free now and can do just about any exercise without pain. To help maintain I use a foam roller. I put the roller on the floor, get down on my knees and roll the inside of my elbow back and forth over the roller. Works great. I also do it for the front deltoids when they're sore.
good luck with that.
