What is the relationship between allergies and headaches?

The relationship between allergies and headache continues to be controversial. Many patients with migraine headache attribute their reactions to certain foods as being an allergic condition. In most cases this is not correct.

  • The sensitive nervous system of patients with migraine may allow them to have attacks provoked by certain specific smells or lighting situations. When a true allergy exists to a compound in the air, the nasal or respiratory tissues react because of the white blood cells or inflammation involved in allergy.
  • At times migraine and other headache patients may get headaches related to allergic problems.
  • Some migraine sufferers will experience nasal congestion or sinus type symptoms as part of their migraine attack.
  • These headaches should not be confused with “sinus headache” or “sinus infection” but diagnosed and treated as migraine.
