MSN Healthy Living - 12 Symptoms to Never Tough Out – Sudden Headache
A sudden, severe headache that reaches maximum intensity instantly should always be checked, says Dr. Mark W. Green, MD, director of the Center for Headache and Pain Medicine and Professor of Neurology and Anesthesiology at the Icahn School of Medicine at Mount Sinai. "A cerebral hemorrhage is always a concern and cannot be excluded even if the headache goes away on its own." Small hemorrhages may seal up on their own and go away quickly, but it doesn't mean the next one won't kill you, says Dr. Green. On occasion, migraines can feel explosive, and not all sudden "thunderclap" headaches are serious, but you should get to an ER immediately to rule out a hemorrhage, says Dr. Green.
