I completely relate. I’ve been sent to several ENTs and an allergist and so far have found no treatment that works. I’ve been on just about every otc allergy med and was prescribed 7 different nose sprays. None of them did one bit of good. The allergy test showed no allergies. This all took place over a period of 11 months. Right now I’m in the middle of a steroid pack and so far that’s not the answer but I’m going to finish the pack just to see. Not very hopeful. I don’t know how to help you, but I do relate.
