Hello. I Went For A Bicycle Ride On Hot And

Hello. I went for a bicycle ride on hot and humid day. About 5min into the ride both sides of the back of my began to throb painfully (location near the area behind the ear lobe but further out onto to boney areas just above the neck) I have never had a headache like this before. It did stop for a few minutes but come back. Eventually it went away completely. My doc wants to do a cat scan of my head.
