My IT band problem was on the outside of the knee right at the bend of the knee. The pain area was about the size of a nickel. Mine would actually act like a locked up knee. I could not bend or straighten it and the pain was intense for about 15 minutes before it would relax. It happened once on the PT table during a stretching exercise. I hobbled my way downstairs to the OS office and that is when they diagnosed it as IT band syndrome. My PT did lots of massage and stretches to try to work it out. After PT ended, I just quit doing the things that made it hurt. I never tried to work back into any of those activities because I was scheduled for the revision.
