Hi sue.
Im getting mine from a sister who works in the pain department she seems to know what shes doing . She told me that the first session could cause problems thats why they only use a small amount of needles . It was interesting talking to her because she knows all about AS she used to work as a surgical sister doing the spine operations for AS and was saying about how many fail she advised me not to risk it unless Im having other problems like breathing or eating. I will let you know how its going Ive got to go every Friday for 6 weeks.
