Wow. If you’ve tried all those things you’ve done most everything short of going to a Doctor, which seems to be your next step. However, one more thing before that would be: Nasonex. It’s a Nasal Spray – goes right into the nose! It’s often recommended by doctors. It’s like a decongestant/anti-inflammatory for the nose!! It’s great too, because it’s local, not systemic. That or something similar is worth a try. [Also.. you need to be consistent on the allergy meds. Maybe try another brand and stick with it a little bit.]
