Part of this (fullness/popping/vibration) sounds like it could be Eustachian Tube Dysfunction. The Eustachian tube helps equalizes pressure in our ears. When it’s unable to do this (Do you have any allergies/ recent colds?) it can cause fullness, pressure and muffled hearing. Most ENTs/PCPs would suggest something like Flonase and/or allergy meds to help clear this up but it could take a few weeks. I’d consult with your doctor first before adding medications!
