Yes ma'am, not a problem! I have always been amazed at the similarities and differences, in our stories. No, an adjustment takes only about 2 minutes, with the use of a little mechanism containing magnets, my surgeon compared it to a "compass". A revision is a surgery for identifying and/ or fixing problems. Your angst with this whole hydro thing, my last bout, in Feb., almost drove my lovely wife crazy, as this was her first time dealing with it/ me.
