The common clinical causes of headache when the face is exerted are trigeminal neuralgia, temporal arteritis and temporomandibular arthritis. 1. Trigeminal neuralgia: mostly attacks on one side. It is often characterized by electric burning, pinprick, cutting or tearing pain. It can be accompanied by facial muscle twitching, tearing, salivation, facial flushing, conjunctival congestion and other symptoms. Vascular compression is the most important cause of the disease. The pain can be triggered by compression aggravated by facial exertion. 2. Temporal arteritis: it is a kind of non-specific arteritis, which most often violates the temporal artery. Systemic symptoms may appear in the early stage, involving multiple joints. After several weeks or months of systemic symptoms, painful arteritis may appear, and eye pain is the first symptom of this disease. Eye pain is the first symptom of the disease. It can be manifested as a symptom of pain when the face is exerted. 3. Temporomandibular arthritis: It is a syndrome of pain, impaired movement and other symptoms caused by temporomandibular joint dysfunction or structural damage. The pain is located deep in front of the ear and can radiate from there and is dull in nature. Pain can be induced and exacerbated by forceful facial movements such as chewing, talking, and clenching teeth. The pain may also be caused by other reasons, and it is recommended that the patient should consult a doctor in time to clarify the cause and give targeted treatment under the guidance of the doctor.
