I know the title sounds dramatic! DP has had persistent headaches for a month now, particularly in the morning. He's otherwise healthy and has been making sure his fluid intake is good to rule out dehydration. He went to the GP who couldn't find anything wrong so is sending him for an urgent MRI scan. Obviously he's panicking like mad and I'm trying to reassure him its probably nothing serious. Anyone else suffered with constant headaches and found a cause/anything to help?
