thank you for various replies, i have taken some painkillers, not sure if they will help, getting a doctors appointment may prove beyond me, and the pain goes across the base of my spine, some parts too difficult to reach.
Have had it before, this time has come on very quickly. Knees in bad state too, left one been giving me merry hell for months. Last time i did see a doctor she said its age related, but i have been told that piece of unhelpful info since my 40's.
