My ears feel like they are stopped up, hurt, and pop. i've been to 3 docs (said they looked fine). history of middle ear and fluid buildup problems. ?

Pop Pop Fizz Fizz...: "There's more than meets the eye" -anon (and a feeble mind, I might add). OK so it looks OK. You probably need a test to measure the reactivity of your inner ear structures as well as how your ear drum is functioning ("Tympanometry"). These help measure the pressures, etc inside that may be causing your symptoms. Go see an ENT doc or Audiologist. And take care if you fly or drive to altitude.
