Signs of Allergies

You might know some of your common headache triggers — maybe you are likely to get one if you skip a meal or don’t get enough sleep. But you may not realize that two kinds of headaches — sinus headaches and migraines — are linked to allergies.


Find an allergist

A sinus headache usually involves pain localized over the sinus area. You may also experience pain in your face along with or instead of a headache.

A migraine headache is a usually a throbbing pain on one side of the head. Light may make it worse, and you could also experience nausea.

Allergy headaches can be very painful and disrupt your daily routine. Your board-certified allergist can help you control your allergies and get relief from this pain.


A sinus headache is caused by swelling in the sinuses that blocks the openings, preventing drainage and causing pressure to build up. Common seasonal and year-round allergens like pollen, mold and pet dander can cause your body’s immune system to react with a sinus headache, even if you have no other allergy symptoms.

Migraine headaches can be caused by many factors, including genetics.  Environmental allergies and food intolerances have been linked to migraines. If you suffer from recurrent migraines, your allergist can help you determine whether you are sensitive to common food allergens like peanuts, eggs or milk.

How to Get Tested

If you’re suffering from sinus headaches or migraines, your board-certified allergist can help you determine whether they are caused by allergies. Your allergist will take a detailed medical history and review your symptoms before doing allergy tests.

The most common type of allergy testing is skin testing, which is fast and accurate. Your allergist may also conduct blood testing or a food challenge to complete your diagnosis.

This process helps identify the specific triggers that are causing your symptoms. Once you know your triggers, you can work with your allergist to develop a treatment plan and find relief!

It Could Also Be…

There are many different types of headaches and many potential causes. If your allergist rules out allergies, ask what else might be causing your headaches, such as:

  • Alcohol
  • Blood clots
  • Brain tumor
  • Carbon monoxide poisoning
  • Changes in sleeping or eating
  • Cold or flu
  • Concussion
  • Dehydration
  • Emotional or physical stress
  • Glaucoma
  • Stroke
  • Teeth-grinding at night
