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.

By Mayo Clinic Staff. Print. Cluster headaches, which occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.
