The article echoes how I think a lot of us who have a medical condition feel. We are always looking for the latest research into how to "fix" ourselves. On the face of it, this new information would lead me to tell my wife to not be so visibly concerned about my various complaints. But is it just more pap from scientists trying to get their names in the papers?
Meanwhile, I will keep reading the stories, looking for the magic breakthrough that will cure all of my ills with the minimum of effort on my part. And I will keep doing my exercises.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
