I've been having headaches for as long as I can remember and never really wondered why. I also get the odd migraine, which is usually stress or menstrual related.
My mum always had them so I just figured that headaches are in my genes.
DH thinks I may be allergic to something which is triggering the headaches.
Would my GP refer me to an allergy clinic as I've read that the online ones aren't very reliable.
