Somatic dysfunction: Treatment of certain conditions may provide long lasting pain/symptom free interval. By not addressing the cause & prevention, symptoms are bound to return. Either way, it sounds like a success story so far; you were able to go without pain meds for a month by receiving a benign treatment. Go back & tell your do you want the pain gone now! & don't want it to ever come back.
