RCVS is known to cause thunderclap headaches, and can be brought on by reactions to drugs, including cocaine and certain antidepressants. No case of RCVS has ever been associated with pepper-eating.
Ed Cara reports: For one brave man, eating one of the hottest peppers in the world came with an unexpected side effect: Days of splitting headaches that prompted a trip to the emergency room.

And cayenne peppers have been rarely linked to heart attacks or suddenly constricted arteries near the heart … (read more)
