Lower back pain.

Lower back pain is. I was just sitting there in the corner in the dark waiting to get you. And the physical pain of when it happens is terrible, obviously. But what's worse is the anticipation of when it could happen. Right. So you don't want to set it off because you don't want to feel that way. But now you're trying to walk on eggshells in your life to not set it off. But eventually it's going to, because your body never stays statically. There's no maintaining. Right. Either getting better or worse in life. There's no static. So eventually something's going to set it off if you don't take the time to specifically correct it. And the cause to make sure it doesn't come back. These lower back pains can come from a lot of different reasons. Right. It's not just one or two.
