Anyone had a Thunderclap headache? Recently I had the worst headache of my life. I had a crushing head pain like someone was pushing down on my head with a ton of bricks. This pain escalated to attend in about 30 seconds. I also had double vision, stiff arms, wobbly balance, and shaking of my arms And body. I also had fever. I finally finally went to sleep and when I woke up I had my normal classic Migraine. The double vision lasted a day and the headache lasted three days. From what I researched I had a Thunderclap headache. Anyone ever had this type of headache?
