twiglett, don't know how close Osteopathy is to Chriopracty (sp?) but I have visited the Chiropractor for the first time this week, initially for a pain in my lower back with a follow-up appointment two days later and inbetween appointments had my neck injured at the hairdresser so the follow-up appointment involved alot of work on my neck. My lower back was slightly worse after the treatment and my neck has been really sore, had difficulty sleeping last night, however my lower back feels loads better now and hopefully my neck will improve too.
My Chiropractor did warn that it would get worse before it would get better.
Hope you are more comfortable soon!
