Cluster Headache

Cefalea en racimos

What it means

A cluster headache is an uncommon type of headache. It is one-sided head pain that may involve tearing of the eyes, a droopy eyelid, and a stuffy nose. Attacks last from 15 minutes to 3 hours and occur daily or almost daily for weeks or months, separated by pain-free periods that last at least 1 month. MedlinePlus says the headache tends to happen daily at the same time of day and commonly strikes 2 to 3 hours after you fall asleep. Cluster headaches may be confused with other common types of headaches such as migraines, sinus headaches, and tension headaches. MedlinePlus lists histamine headache and Horton's headache among the alternative names. In Spanish the term is cefalea en racimos; the MedlinePlus en español encyclopedia article is titled Cefalea en brotes.

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
