MT's Elbow pain

[Xenu]

I've had pain around my right elbow for some months now. Bomes and goes. Icing and/or wrapping it in the evening helps minimally.
It's the right elbow, medial, both inferior, superior and directly over the medial epicondial (i think).
I believe it originally happened when putting an elbow in someone's glutes.
Then I thought I was aggravating it by leading off with my fingertips instead of my palms.
During my massage sessions, it's only bothersome during long strokes down the back. (and more glute-work)
It doesn't always hurt, but I'll lift something, not thinking and wow, it's THERE!
As an example, if I scoop up my fat cat under my right arm, the pain is bad then.
My next step is to get an aerobic step to help me get up over the thicker folks when I'm working on their backs.
So, what should I be doing?
