This depends on the acupuncturist you go to – and the system of acupuncture that they practice.
That said, acupuncture does not have side effects and can be used for any condition to help speed up healing or be the main method of resolving a health condition; it all depends on the ability of the practitioner.
Results are usually the only side effect, meaning, you get what you came to the acu doctor for – which is great!
In England however, there are a huge amount of systems of acupuncture, and not all acupuncturist ability is the same – just because your doctor is chinese or korean does not mean they will be good, and the same goes for western doctors who do a weekend course in acupuncture and think they are specialist in needling patients.
