Allergies and Headaches
Many people complain of headaches, and for some, the cause may be attributed to an underlying allergy. The most common forms include sinus headaches and migraines.
There are four different sinus cavities found within the human 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, fluid and pressure can build causing facial pain and/or headaches. Another tip for determining if your headache is allergy-related is if you notice your headaches accompanied with other symptoms such as 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 sunlight and accompanied by nausea. Some migraines can be provoked by food additives or naturally occurring food chemicals in non-allergic individuals.
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, or allergy drops, and medication may result in significant improvement of their allergies and migraines.
