Generally a course of treatment is accepted as being 8-10 individual sessions. Very commonly your condition may resolve in fewer than this, but if it is a long standing condition then it would not be unexpected to require considerably more. Initially you may be asked to attend for treatment two or three times a week, and then as symptoms improve, weekly treatment would be likely. Your first appointment may last for close to an hour but subsequent visits may only take 30 or 45 minutes.
