I supect you can probably go on the NHS but I imagine there might be a waiting list for those. There are lots of private ones - www.yell.com will have a list in your area - but they cost.
Yeah i know, im not bothered about paying but i wondered if i had to be reffered first or if i could just go. I mean can i diagnose myself saying that i need my back cracking? or does the doctor have to do it?
