Anyone suffer from SPD? I'm beginning to think that's what's going on with me. My groin area and hips hurt extremely bad whenever I'm walking, try to roll over, or move one leg up. When I roll over in the middle of the night from my right side to my left, my bones make a loud pop sound. Once I actually lie on my left side, it hurts so bad that I have to roll back over. I didn't have this with my first (almost 7 years ago).
