Try a little gentle antihistamine like Benadryl. Sounds like your ears just stopped up. I have that, too, after I smoke weed. I think it's allergies. And 50mg of Benadryl usually clears it up. Doesn't sound like anything bad enough to go to a doctor with unless you have pain or it's just driving you crazy.

You could also try chewing gum and yawning/stretching your jaw to see if that'll open up your Eustachian tubes similar to the way you relieve the ear pressure when you go up in a plane.
