I have a fizzing in the left side of my head...I have had one sinus infection after the other and found out I also have allergies. There is pain in my left eye...I always seem to have my left nostril clogged...I have used different meds, allergy, sinus spray, etc. but it keeps coming back....I have tinnitis, but this other fizzing is driving me crazy.Can there be something other than just allergies or sunusitis?
