Hi Roger.
I was really sorry to to hear about your back problem, like I said I have a similar, if not quite as bad, problem with a bulging disc in my back. Numb toes on one foot and muscle spasms in my lower back whenever I bump into anything, no pleasant. The upside was the Temazepam the doctor gave me, if you can't sleep it puts you under in 2 minutes flat!!! Keep your chin up and keep watching, and posting, on the forum. I will keep a set of panels warm for you.
