Allergies and Headaches
Many people complain of headaches, and for some, the cause may be triggered by an underlying allergy. The most common forms of allergy headache include sinus headaches and migraines. There are four different sinus cavities found within your head:
- Behind the eyes
- Inside the cheekbones
- Behind the bridge of the nose
- Behind the forehead
Typically your sinuses drain through your nose. When a sinus cavity becomes blocked due to allergy, fluid and pressure can build, causing facial pain and/or allergy headache. Sometimes these allergy-triggered headaches are accompanied by itchy watery eyes, sneezing or runny nose.
Some evidence suggests that food allergy, sinusitis and allergic rhinitis may be triggers of recurrent or persistent migraines for some people. Migraine headaches tend to be throbbing, one-sided headaches that are aggravated by light and accompanied by nausea. Some migraines can be provoked by food additives or naturally occurring food chemicals in non-allergic individuals.
Can allergy drops help improve allergy headache symptoms?
Migraine treatment typically consists of medication to control or prevent inflammation or to treat the migraine episodes. However, for those patients with allergic rhinitis or sinusitis, controlling allergies with sublingual immunotherapy (allergy drops) and medication may reduce both allergies and migraines.
