this morning I have totally, utterly, done my back in. I was just about to sit down - on the loo as it happens! - and I felt this terrible pain. I couldn't stand up, walk or even get downstairs for a long time. I have quite bad degeneration of the L4 and 5 vertebrae according to xrays and these excruciating spasms have happened three times now over the past five weeks. I walk a lot as I don't have a car but when I've walked for about 40 minutes my back and buttock begin to hurt. Could someone please advise me what sort of exercises strengthen the back please at my age? Does pilates help?? Thank you for ANY reply, really need someone of similar age who knows what I'm talking about.....Thank you so muich. PS: I am 68 and would ideally like advice from someone of similar age on here who knows exactly what I'm talking about. That's if there actually is anyone my age of course!!
