I developed post nasal drip 2 years ago which i assumed was due to allergies, even though i never had any before (im only 24). I was allergy tested and only slightly sensitive to mold and dust mites according to my allergist. Within the past year I developed extreme forehead tightness that radiates to my temples and to the top of my head. I had a ctscan done which was clear besides a deviated septum and mucosal thickening in my sinuses. So, i had septoplasty done and nothing changed! Does anyone know why this can develop? I've tried every med and nothing works, even pain meds don't alleviate the pressure/tightness feeling.
