Hi, I strained my quadratus lumbar. I was wondering how long this type of injury takes to recover from? I don't think the strain is severe. It doesn't affect me THAT much but I would rather it not affect me at all before I start lifting again. Also I was wondering what this muscle is usually strained from ei. deadlifts ect ect. I am not sure how I strained it because not one exercise I remember doing hurt a lot. Thanks guys.
