Hi, this morning at the gym I injured my lower back. I was doing leg presses (the lying down type). I did a couple of sets of 12 and half way through the 3rd set (pressing 120kg), when I was pushing out I felt a ?pop ?tear something in my lower back. Immediate pain and loss of leg strength. I stopped immediately. Lower back is very sore. Central pain. Radiating around hips and some nerve shooting pain in legs. I have gently stretched lower back, taken anti inflammatory's and put ice pack on area a couple of times since it happened. Any idea what I might have done? Any other things I should be doing to treat area?
