I had sudden severe migraines that were characteristically different than any that I had ever had before. They were on the front, side and back of my head. No pain pills worked on them. I had a major stroke on my left side about 3 weeks later which were the cause of continuing severe migraines on the left side of my head the last 5.5 years.
i had been having pain in back of my head, left side at the bottom before i had stroke on right side of brain
Stroke headaches are more typically sudden severe ones. If you have concerns, please contact your doctor.
