Unfortunately, there are no specific medication or treatment options available for primary thunderclap headaches. When it comes to secondary-type thunderclap headaches, treat the underlying cause as soon as possible. Contact your doctor or go to the emergency room right away. Once resolved, the headache should be reduced or completely gone.
The worst pain settles a few minutes after the peak, but moderate to severe pain may still be felt for hours after. Bed rest, hydration, and OTC pain relievers can help. For severe pain, your doctor may prescribe stronger pain relievers such as opioids.
Additionally, it is best to avoid exacerbating substances and activities. Do not take medications that can constrict blood vessels, such as steroids, anti-migraine medications, and cold preparations. Avoid stress, heavy lifting, and vigorous exercise as these can trigger headaches and RCVS.
In summary, a thunderclap headache is a serious condition. Those who experience it are not simply being sensitive or overreacting to the pain. It can be a sign of something much worse, such as a ruptured brain aneurysm or meningitis. So, it is imperative to seek medical help as soon as possible to prevent further injury or death.
