I'm sorry to hear you're having this problem, I hope it goes away but if it doesn't you really should see the ENT. I tend to have issues with my ears/sinuses, pain and loss of hearing at times, apparently it's a problem with congestian in my tiny eustacian tubes. I have found that nasal decongestants (eg Beconase spray) are effective, but you would need to check if they 're ok in pg. When I was pg I used a saline nasal spray religiously (Fess) which made a huge difference. And there's always the rinse option, the kit comes with a squeezy bottle and instructions, worth a try IMO given how good mild saline works for problems with the mouth/throat.
