Rmaddock,
Sorry for your back problem, sufferred with the same for years (from apprentice days..... many years).
Was told of a treatment that worked for a number of friends, so I gave it a try. Gentle, no harsh medicine in any shape or form.
Had an hours treatment on 2 Sept, result is almost magical, no pain or restriction in movement. Oh the delight of free movement with no pain!
For info look up Bowen-Therapy.
Usual disclaimers, I'm just a very satisfied customer, well worth a serious look at.
Good luck,
Regards.
