headache

So I've had a headache for 3 days I've taken Tylenol it goes away then comes back. Called the hospital earlier and she told me to take another so I did. It went away again for an hour then came back. Called again and she told me to take two more. I said what if it comes back tomorrow and she's like call your doctor. He's out of town, why do you think I'm calling you!!  idk if this is normal or not but it's completely knocked me on my ass, I'm a very active person and I haven't got out of bed all day. What should I do?!
