My brother has had somewhat similar symptoms for years. About a year ago he got a cranial x-ray for unrelated reasons, and the doctor discovered one of the largest sinusitis infections he'd ever seen. (Unfortunately, due primarily to living in a country without accessible medical care -- the United States -- he hasn't followed up on taking care of it.) Also, make sure you keep an extremely clean and airy environment. Dust, mold, pollens, etc. will aggravate the condition.
