HI. I have been getting a lot of relief lately and have increased my walking up to 3.2 miles a day. Since I saw the ortho doc, who said I didn't have any major structural damage things have definitely improved. He did say, however, that what I did have was coming from my sacroiliac joint. I have decided to do a few minor PT exercises for that. The difference this time is that it is actually helping. In the past, I went to a PT, had all kinds of elaborate routines and nothing worked. Now, I do a few of my own, at home, exercises and I am good to go. Does that mean that I have bought into the structural versus the psychological? In my mind, I don't feel that way because I am entering into this realizing that it is not something major and a bit of tweaking helps.
