hi, Cluster headache is a condition that involves, as its most prominent feature, an immense degree of pain that is almost always on only one side of the head.Excruciating pain in vicinity of eye. Tearing of eye, nose congestion, flushing of face. Pain frequently develops during sleep and may last for several hours. Attacks occur every day for weeks/month, then disappear for up to a year. 80% of cluster patients are male, most ages 20-50. Trigeminal neuralgia can also bring on headaches with similar qualities. However, with trigeminal neuralgia the pain is mostly located around the facial area and is described as being like stabbing, electric shocks, burning, pressing, crushing, exploding or shooting pain that becomes intractable. Sinus headaches are associated with a deep and constant pain in the cheekbones, forehead, or bridge of the nose. The pain usually intensifies with sudden head movement or straining. The pain is usually accompanied by other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, and facial swelling. -Over-the-counter pain medications (such as aspirin, paracetamol/acetominophen, and ibuprofen) typically have no effect on the pain from a cluster headache. Cluster headaches do not respond to basic biofeedback.Medications to treat cluster headaches are classified as either abortives or prophylactics (preventatives). In addition, short-term transitional medications (such as steroids) may be used while prophylactic treatment is instituted and adjusted. With abortive treatments often only decreasing the duration of the headache and preventing it from reaching its peak rather than eliminating it entirely, preventive treatment is always indicated for cluster headaches, to be started at the first sign of a new cluster cycle. thankyou.
