Have you ever been watching NYPD Blue and said, "Wait, was that a nipple?" Sure, we have all been there. You should get yourself a TIVO. With this miracle device, you can do a quick frame by frame rewind, confirm the nipple and still not miss any of the show.
I cannot believe I lived without one for so long. Seriously, get a TIVO. Life will never be the same.
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.
