As in, lower lower back, or upper butt, around where the pelvic bone is. I'm pretty sure the cause is bad form deadlifting. I've been to a coach and I think I have the form down. My plan was to wait until the pain is totally gone, the muscles healed, and then start over with very low weight until I am absolutely sure that I have form correct and then slowly add weight. Well, it's been eleven freaking days since I last lifted and my damned back still hurts. Is that normal? I am frustrated here. I've tried stretching but that seems like it makes things worse. Advice?
