Do not take sudden, unusual headaches lightly, especially those so intense they feel as though a blunt object has struck the head. Medical experts liken the pain to being struck by lightning.
The headache may subside just as suddenly, leading those who experience it to dismiss it as a migraine or attribute it to physical exhaustion or emotional stress.
After taking medication and resting for a while, they resume their daily routines, giving little further thought to the episode.
