You could see a doc. Prednisone (a steroid) may help but most likely you're going to have to wait it out. I'm going through the same thing right now. It's been two weeks and the pressure and ringing is driving me up the wall. I basically have lost most hearing in that ear. From what I understand these things can take months to resolve. At least the pain aspect of it went away within a few days.
You could try antihistamines and decongestants but they haven't been doing much for me, really. I haven't been shooting since this started, as I don't know if the noise stress would prolong this. OTOH, maybe it would help unblock it!
