As an aside, my neck is now fully red. Besides liking NASCAR and The Mullets tv show, I see from that site that "coke" is the generic used primarily in the South. To further this line of thinking, I am listening to a lot of country music again. "What Was I Thinkin'" and "Celebrity" are great songs.
Maybe some travelling hillbillies had a baby in the same hospital the day I was born and I was switched.
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.
