some smells can trigger or make my migraine pain level go up...but they've been real.
Check this out,maybe you've gone through it:
(Reuters) - Hallucinated scents such as a burning or rotten smell, or even the scent of foie gras, can be a part of the "aura" that some people perceive before a migraine attack, although it is rare, according to a U.S. study.
About 30 percent of people with recurrent migraines have sensory disturbances shortly before their headache hits, known as aura, but these are usually visual, such as flashes of light or blind spots. Tingling sensations or numbness, or difficulty speaking or understanding language, may also appear.
But the study, conducted by Matthew Robbins and colleagues at the Montefiore Headache Center in New York, found that a small number of people described smelling scents in conjunction with their headaches.
"It's uncommon, but distinctive," said Robbins, noting that disturbances in the sense of smell, known as olfactory hallucinations, have not been covered in a systematic review of medical literature before.
