What can you do for a sick headache?

Migraine. Sick headache is another name for migraine if recurrent and longstanding see migraine treatment or see a neurologist.
Vicks. In addition to Tylenol (acetaminophen) and Motrin for the treatment of headaches,, one thing that I do when i get sinus pressure headaches is to rub Vicks on my forehead. Give it a try! it works for me.
Vague. Certainly need a lot more info. Duration, intensity, location. Keep a pain diary if you can and document your headaches.
