Hemicrania Continua is a rare type of chronic headache that is characterized by continuous, unilateral pain on one side of the head. It is considered a primary headache disorder, meaning it is not caused by an underlying medical condition. The pain experienced in Hemicrania Continua is typically moderate to severe and can be accompanied by other symptoms such as tearing, nasal congestion, and drooping of the eyelid.
What sets Hemicrania Continua apart from other types of headaches is its constant nature. Unlike migraines or tension headaches, which may come and go, the pain in Hemicrania Continua persists without remission. However, it does have periods of exacerbation, where the pain intensifies.
The exact cause of Hemicrania Continua is unknown, but it is believed to be related to dysfunction in the central nervous system. The condition is often responsive to a specific medication called indomethacin, which can provide complete relief from symptoms.
If you experience persistent, one-sided headaches accompanied by other symptoms, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
