I'm a 26 year old male and since October 2006 have been experiencing 24-7 sinus pressure in
the upper corners of my nose (always one side at a time), but NO allergy symptoms
(i.e. no running nose, sneezing, coughing, itchy nose/eyes/throat, etc).
The pressure is so bad that it presses back onto my brain, causing terrible lightheadedness, forgetfullness, and general mental impairment.
