France. While Spain was building its New World empire, France was also exploring the Americas. In 1524, Giovanni da Verrazano was commissioned to locate a northwest passage around North America to India. He was followed in 1534 by Jacques Cartier, who explored the St. Lawrence River as far as present-day Montreal. In 1562 Jean Ribault headed an expedition that explored the St. Johns River area in Florida.
The most common autonomic symptoms that a cluster headache sufferer may experience are pupil constriction, conjunctiva redness, a drooping eyelid, and a runny nose. In rarer cases, autonomic symptoms of blushing and sweating may appear on one side of the head as well.
Autonomic symptoms are common with different types of headaches including migraine and trigeminal autonomic cephalalgias. Look at yourself in the mirror when you have a headache and observe changes such as facial flushing, eyelid drooping, or tearing. Pay attention to sensations of ear fullness or nasal congestion.
