Steely Dan is coming to my town next week. My wife and I have lawn tickets, so I get to lay down in the sun for a few hours and listen to some of the greatest music ever written. Michael McDonald is opening. At first, I was all "OH NO! Not the 'Yah Mo Be There' guy. Then I remembered that he was part of Steely Dan on their early albums. It should be a good night.
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.
