I’ve read that when you have a muscle tear, the muscle doesn’t heal with muscle tissue, it just fills the gap with fucking weak scar tissue.
I tore a muscle in the left side of my lower back several years ago (and reinjured it twice). I’ve finally stopped reinjuring it, but nonetheless the left side of my lower back (way down at the hip) still feels different than the right side, and I just know it is holding me back on deadlifts bigtime. Seems like this is because my body repaired the muscle with damn scar tissue.
So is that really how muscle tears work? Are you just stuck with scar tissue there forever? Can’t you ever regrow the muscle like it was? Does this permanently impact your strength?
