Its so frustrating! I have classic migraines with aura's and sickness and over the last year have started to get these long-winded headaches that last for weeks aswell!
It always starts out with a fuzzy head and a dull ache above my right ear, and as the day goes on it gets worse and worse. I got so mad with the pain last week i actually dug my fingers in above my ear where head was hurting the most and now have a really sensitive, sore area about size of 50p!
I've been reading into migraines/headaches and magnesium levels being related and have started to take a supplement everyday and a tablet called feverfew. These are both harmless to your system so doesn't do any harm to try taking them before seeing a doctor!
Hope feel better soon
