 So if someone has sciatica from a disc pinching, you'll use Calmer on them? Is that right? Yes. Okay. If it's been there long enough, actually. So if it's less than six months, not too concerned, meaning if we decompress the disc, if we get it vacuumed back in position, then that radiating pain will go away. You take the pressure off the nerve, it's not pinched anymore, it heals.
