Hi Ceri,
Originally I had accupuncture for Osteo arthritis way back in 2005 but am now having it for RA too, I cant take any anti inflammatories so it was suggested I try accupuncture, I felt relief with no side effects from the first session so cant tell you if what you are feeling is after effects of session or not, I just know if I'm having a flare of either of my arthritis problems it helps enormously. Hope it works for you too....Eileen x
