There are usually no negative side effects. As energy is redirected in the body, internal chemicals and hormones are stimulated and healing begins to take place. Occasionally the original symptoms worsen for a few days, or other general changes in appetite, sleep, bowel or urination patterns or emotional state may be triggered. These should not cause concern, as they are simply indications that the acupuncture is starting to work. It is quite common with the first one or two treatments to have a sensation of deep relaxation or even mild disorientation immediately following the treatment. These pass within a short time and never require anything more than a bit of rest to overcome.
