I'm feeling better this morning... I've been doing the heat thing as much as I can. Course, I was cleaning up the garage yesterday afternoon and that could have made it worse. I'm just trying to take it easy for now. Moving around and such. I've always had issues with the left side lower back. I've got to agree it's probably posture and too much sitting. I'm going to try to walk on the treadmill at an easy pace to keep moving around.
Thanks, C. Tim Conway is an absolute hoot. His book 'What's so Funny?' is hilarious, especially the antics with Carol Burnette and Harvey Korman. He lived to make Harvey break up during skits and played pranks on him in real life.
