Obviously the number of treatments vary with different conditions and individuals. Chronic problems generally require more treatment than acute ones.
Patient are urged not to enter an Acupuncture program with the thought of "taking a few" to see what will happen. This would be comparable for a physician to recommend a two hour operation only for the person to say they will try 45 minutes of it to see how it does. Patients are always encouraged to be patient with the healing process.
