I had heard about a town in northwestern NJ that was abandoned by its residents. A hydroelectric dam construction project was going to result in a submerged town. The project was the ill-conceived Tocks Island Dam. The government had bought up the property that the dam would have flooded. Wallpack Center was at ground zero. Of course the residents were asked to leave and they did. The dam project was scuttled because of environmental concerns. The property owners however, were never allowed to return.
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.
