Thank you for your concern and good wishes ((sundog)). I decided to go tomorrow to my family doctor and then go for Xrays. I just want to make sure there's nothing like a disc problem - don't want to injure myself further with exercise. If I get the all clear from the Xrays, I'm determined to make my back and whole body stronger again. I've slacked off the last couple years and this is a wake up call for me.
