Doodles, 1983 - Pen and ink, 8" x 10". I was working in the windowless basement of a library and spent much of my time on the phone. I began doodling on a piece of art paper and just kept adding to it over a period of a couple of weeks. This is the result.
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.
