Allergic Rhinitis Can Trigger Migraines

The most likely culprit is histamine. The chemical is released by immune cells during allergic reactions.
"We think that when nasal allergies occur, a lot of that histamine here can trigger that very first response in the development of migraineheadaches, namely vasodilation," said Ku.
That's when blood vessels swell up and stretch. Fred Belcher loves to ski this time of year. He usually suffers later on.
In such cases, you might need steroid nasal sprays or allergy shots, instead of antihistamines. However, it has to be determined if you're having real migraines, or if they are sinus headaches. Best see a doctor for appropriate treatment.
