That depends on each stage and the condition off the patient. Because just most of the times when the condition like arthritis is involved, there is additional conditions, maybe hypertension, diabetes, obesity. So many other health issues. So it varies for individual to individual. It can be 7 to 10 sessions, to 20 sessions, 40 sessions. It is all depending on each individual. In order to determine how many sessions are required, a thorough investigation has to be done before starting the treatment. Based on the condition and the stage the patient is suffering, the doctor will determine how many sessions are required. In my opinion, a minimum of 12 to 15 sessions are required and it can go upto 25 to 30 sessions of acupuncture to manage the pain. Even after finishing the course of the treatment, acupuncture can be continued for however long you wish to, because it helps to reduce the dependency on the medicine It helps to reduce the pain keep it at a abase minimum and carry on with your day to day activities very comfortably, but the only thing is the frequency of the acupuncture treatment will be quite less. Like for example once a week or once in 10 days, or I do once in 3 weeks also. So it depends on each individual how many sessions is required and it can go as long as possible till the disease is there and many of the arthritis which cannot be reversed, which cannot be completely healed, which can be just managed, acupuncture can go among depending on the condition and the doctor.
