I'm so glad you got some relief.
I am walking proof today that manipulations do work.
I have sciatica problems, bursitis, four herniated discs (L1 - 4), a right hip that likes to pop out on its own, and several of the arthritis', so know pain well. Manipulation is a godsend. I hate meds so only do Aleve or Advil. Lots of heating pad time and ice bag.
I no longer cross my legs except at the ankle. I was told placing the ankle of one leg over the top of the knee of the other was ok. Not ladylike, but works. Also, one of the worst culprits is sitting with one leg under you. Bad, bad habit. Twists your hip and spine terribly.
