Thanks for the input guys

Brought an expensive chair (cheap on fleebay), I'll try sitting in that predominantly, along with a twice a day routine of recommended stretchs, 2 half an hour walks a day, hot showers and drinking plenty of water, see if I can't get my tos in check. Pretty much except that I'll never work as a mechanic again or ride my bike, but would be nice If I could have a go on my guitar and play some video games though (sad I know). Anything else people recommend?
