This forum is for questions and support regarding migraine and headache issues such as: abdominal migraines, headaches caused by allergies, cluster headaches, headaches, headaches in children, migraine headaches, sinus headaches, tension headaches, visual disturbances.
I don't think the medical community can answer this for you because there is so little research into this complex trigger. Hair, ear canals, and sinuses each have their own receptors for external stimuli.
