Thanks all for your replies. I must admit I do feel humbled by some of your stories and what you have to go to and think I should just 'shut up'!! I do think the site is great and it is good to vent because I think my partner and friends are sick to death of me going on about it - I have one friend who still can't understand the fact that my back problem causes so much trouble with my legs!
And PALady - I think I have just found a PT who is really good and hopefully will help. I havn't dared go near one for over a year becuase I am convinced the first one I saw made things way worse. This one treats your whole body with a mixture of PT/reflexology/eastern medicines etc. I now do a lot of gentle pilates - the whole problem probably starting from weakness due to several abdominal surgeries over the years. Again my thanks.....
