I've used google to self-diagnose myself, and found that I have some sort of sacroiliac joint injury. I know pain in the SI joint is common among members of this forum, so I'm making this thread into an informative resource on dealing with it. As of now, I haven't done any research and I'm about to go to bed, but please post any information you guys have about SI joint injuries. If I remember correctly, Ascendant wrote an in-depth rehab program for MoM a few years back. Hopefully someone can dig that up. I will be saving the second post of this thread so that I can fill it with information later. My situation: I was off of lifting for 3 months, and planned on returning with the SS program. As soon as I began back squats I started to experience major pain in my lower right back/hip area. The pain is bad through-out the lift, but especially at the top (when I'm completing the lift). Squats seem to trigger the pain, and all of my proceeding lifts are uncomfortable, whereas they feel fine if I do them before squatting. As far as I can tell, my form is solid (probably better than it ever has been since I began squatting 4-5 years ago).
