Hard to tell
You may have allergies
(dust, chemicals you use) or potentially gerd (reflux
) that may cause similar problems.
It's worth checking out in your physician's office. I'd recommend keep a diary of potential allergens and also take anti-gerd measures (elevated the head of bed, go to bed at least after 2-3 hours since your last meal, avoid foods that are known to cause gerd - spicy, greasy, etoh/caffein.
