A few of the more commonly reported side effects of Dysport for TMJ include headaches, drooping eyelids, queasiness, and flu-like symptoms, all of which should fade within a few days of treatment. Some other temporary side effects you might experience include pain, redness or bruising, and paralysis around the injection sites. If you have any concerns about side effects or the effectiveness of Dysport for TMJ therapy, we encourage you to bring them up with Dr. Dhariwal during your consultation at our Elk Grove, CA office.
