Exploding Veins!!

I have a problem that maybe someone out there has had some similar trouble with, or just might be able to tell me something I don’t know. When I do a lot of squatting, I get bruising and sometimes burst blood vessels on the back of my knee and lower thigh. It often happens when I’m going very heavy (350+ range) for zercher squats. Does anybody have anything similar that they can think of that has happened to them? I don’t wanna give up squatting, or especially zercher squats, so maybe some sort of muscular balance adjustments are in order. Any takers?

I don’t have an answer for you, but I’ll give you a bump because I’m interested to see an answer to this one.
