Hi All: So since finding the Sarno book almost two weeks ago I had a gradual decrease in my pain symptoms and then last night, BAMM! I got intense pain in the back of my leg and today it's moved to my left glute. I know this is an extinsion burst. I've been able to beat the headaches and this is just one more pain, but boy did it send me right back to fear. I am getting back to my normal life and not obsessing so much about the pain. I am doing things I enjoy and feel much happier. This was just a little scary. I know progress in not linear and need to be patient. I guess I just thought I'd keep getting better and better every day.
