Hi- Alophysio and thanks for taking interest and providing prompt solutions.

"have you got a CT or MRI scan of your back?"

No I haven't got it done yet. should I go ahead with it? and if yes should i ask for whole back or lower back CT and Wikipedia reference-linkMRI? as i have tight inner thighs and hamstrings too so no scan for that area?I have never got it done before so please excuse my lack of knowledge.Yes- I did show a physiotherapist a few years ago he did some hydrotherapy putting me in a hot boiling water tub which he said would relax which they did from the severe stone like thighs. Also he reffered me to a sports injury doctor who asked me to do some "lumbersocal" or something x-ray for lower back may be. I got it done and the report says its okay .

".. There is only limited information."
Please let me know if i need to do something else or you need more information . I would be grateful.Thanks.
