For most conditions of simple pain, relief should be achieved within 3-4 visits if treatable, for example a muscular spasm or a trapped nerve. Sometimes more sessions are required, but it all depends on how you react to the treatment, how significant the problem is and how long you’ve had it for. At the very least, by the 3rd treatment you should be experiencing a significant change if the therapy is to work for you. But I always give an opinion before treatment starts of the likely number of sessions you will require.
Acupuncture is probably best known as a way to help people control pain. Depending upon the type of pain and its cause, acupuncture can be effective in relieving pain completely or reducing and controlling it, to allow for a better quality of life.
