Usually not. As energy is redirected in the body, internal chemicals and hormones are stimulated and healing begins to take place. Occasionally the original symptoms may 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, especially with the first one or two treatments,  to have a sensation of deep relaxation following the treatment.
