If you have a blocked ear with pressure but no pain or swelling, it is likely a build-up of wax causing the issue. You have a few options to try and alleviate this problem. You can use over-the-counter ear drops specifically designed to soften earwax, such as Murine Ear. Another option is to try using a few drops of mineral, vegetable, or olive oil in your ear to help dissolve the blockage. If these methods don't work, you may want to consider making an appointment with a healthcare professional, such as a nurse, to have your ear cleaned out. Be sure to follow the instructions carefully and seek further advice if needed.
