If you give your chiropractor a call & say, "So this morning I bent over to get something under my bed & my knee bent the wrong way. Like, it bent sideways instead of the normal way. The top part of my body went right & the bottom part of my leg went left, instead of bending forward. I laid on the floor & actually cried from the pain. That's not a good thing, right?"
Your chiropractor will tell you, "No, that's not good. That's very bad."
Then you will interpret what your chiropractor will tell you to mean that your cartilage is not happy.
Your chiropractor will tell you that you can't put weight on your leg until you come see him.
Then he will tell you have an immediate appointment with him to fix the damage to your knee.
If you give your chiropractor a call, you will yell at your knee for making you reschedule your nail appointment & you will have to go to your chiropractor with sad nails.
