I've been having stiffness in my leg muscles. Yesterday, I was not as careful walking, pushing a little faster and something popped behind my leg. Can't pinpoint exactly where it happened because of pain everywhere and I immediately could not put any pressure on leg to walk. Went to ER, had a CT scan. No broken bones. told to follow RICE for 5 days and see if I can put pressure on it. If not, will need to seek additional help. I would think an MRI would be needed. If something is torn, won't it grow back in perhaps the wrong place?
