Don't be silly. I am not affiliated with the goths who hang out at the end of the boardwalk. Yes, rivetheads have made attempts to horn in on my culture. It's attractive to them. Since Evanescence went mainstream, they've been able to buy their clothes at Spencer's Gifts. But just because they read about our ways on Boing Boing doesn't mean they can rock a true neo-Victorian lifestyle. It takes a lot of time and a lot of welding.
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.
