Hey guys. I've been closely following Rippetoe's Starting Strength guide for a few weeks now, and a problem keeps occurring during my squat execution. That is my right knee, just above it, hurts like hell during every squat. It feels as if when I go down / come up [during the squat] it's bursting, and it hurts very much afterwards as well, I forced myself to finish a set and stopped there because I wanted to avoid injury. The same pain is felt when doing a free squat, just not as bad due to the lack of weight. What do you think could be causing this? Is it my form perhaps? I tried widening my footstance (with a lighter weight of course) and doing all sorts of minor adjustments to my form but nothing seems to be working. Should I just suck it up and go execute the squat squinting in pain or is this the dumb thing to do because it's most likely that im injuring myself?
