Arthrocephalgia is a medical term that refers to pain in the joints of the skull, particularly those associated with the temporomandibular joint (TMJ). This condition can result from various factors, including stress, teeth grinding, or jaw misalignment, leading to discomfort and headaches. Symptoms often include pain in the jaw, face, and sometimes neck, and may be accompanied by difficulty in jaw movement. Treatment typically involves pain management, physical therapy, or dental interventions.
