Forget chiropractors, they are better marketeers than we are, they will try and convince you that you need at least 6 sessions to sort your back out.
I put 2 discs out over 10 years ago lifting a particularly heavy carpet. I was lucky that my GP referred me to an osteopath and she clicked me straight back in.
My discs pop out every 18 months or so as there will always be a weakness there, so I phone the osteopath, she cracks me in, I have a day off and I'm right as rain until the next time.
