I have set up a Sciatica Forum. Judging from the volume of email that I get and the couple of hundred of you a day that come through here, the need to exchange information about back and leg nerve pain is pretty great.
The goal is to set up a place where those of us in pain can communicate. Please check it out and let me know what you think. Sign up and share your story, give us a piece of health news or recommend a website that helped your pain.
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.
