Hi, last week I flew home from the east coast to Colorado. about 90 minutes after landing, I quickly had stuffed ears, ringing, and a bit of dizziness. I ve never had trouble with allergies, but my doc said it was allergic rhinitis, & gave me a decongestant, antihistamine, and flonase. I ve also been breathing steam, and started using a humidifier and some nasal gel to moisturize. Approximately how long should it take to improve? I m especially bothered by the ringing. Thanks
