Hi, I have poor posture like so many other quads. While sitting my left hip migrates against the left side of the chair. I went through Tylenol like crazy. It hurt. I placed a foam block at my left hip, keeps it from going left and my pain is much less. Sometimes, not every time pain is caused by positioning.
