So far I have gone to four ENT’s one was at Johns Hopkins hospital. All have said it is eustation tube inflammation swelling from a histamine which means allergy. I have been receiving allergy shots for 15 months but each time the barometer goes up I get more clogged. Also wet weather does it too. I am hoping to find an ENT who will know whether ballooning again will help. I’m desperate it’s been three years of this.
