I took a break from barbell squats. Got diagnosed with tennis elbow, received a cortisone injection, got a medical elbow strap and haven't been doing any heavy back squats in the 3-6 rep range for almost three weeks now. I also ceased to do intense rows and curls as well, just to be on the safe side.
I hate front squats with a passion and really would like to get back into good old back squats, but I'm afraid the tennis elbow will come back.
The tricky part with this condition is that I don't notice the pain right away, but it sets on with a significant delay - took me a while to figure out it's not the bench pressing that causes the pain. Hence it's extremely difficult to gauge what exactly is causing tennis elbow when squatting.
My question: What are causes for this condition when back squatting and how can I adjust my form to prevent relapse (e.g. high bar vs. low bar, wide grip vs. narrow grip, elbows pointing behind vs. elbows pointing to the floor...)
