Cluster headaches are characterized by severe headaches around one side of the eye, which are frequent and short-lived, often unilateral, with no aura, and most often occurring at night. Cluster headache is a type of functional headache, so named because of its intensive headache symptoms over a period of time. The main manifestation is a severe headache around the eye socket on one side, with frequent and brief attacks, often unilateral, without aura, and mostly at night. Some patients may have tearing pain, cramping pain, burning pain and sharp stabbing pain in the periorbital area and the back of the eye, as well as conjunctival congestion, facial warmth and flushing, nasal congestion and mucosal edema. Cluster headaches need to be treated with medications as prescribed by your doctor, which mainly include oxygen therapy, medications including painkillers such as ibuprofen and acetaminophen, and also medications such as ergotamine caffeine tablets, zolmitriptan tablets, and naratriptan, which can help improve the symptoms. Medications need to be used under a doctor’s supervision. Daily life should pay attention to avoid too much fatigue, do not stay up late, reduce the use of electronic products, but also to avoid anxiety, tension and other bad emotions, so as not to trigger cluster headache attacks.
