Ever since I drove over several mountains on Sunday (it’s now Tuesday), my left ear has been clogged. My left nostril has been marginally less open than my right one recently, but I don’t feel stuffed up at all. I tried an ear wax treatment twice and it didn’t help. The strangest thing is that I can unplug my ear with the Valsalva method, but it closes again quickly. I’ve tried chewing, swallowing, ibuprofen, nasal decongestants, and blowing my nose. Blowing my nose has been the most successful at opening my ear, but when I swallow it closes again. There is also some pain in my ear in and off. Please help
