A sensation of blockage in a clear-looking ear is very common. It is often caused by trapped earwax deep near the eardrum, or fluid buildup behind the eardrum due to allergies or cold-related congestion. For potential deep wax, you can try generic carbamide peroxide or olive oil ear drops to soften it. If congestion is the cause, a generic nasal steroid spray like fluticasone, or a brief course of oral decongestants, can help relieve the pressure. Avoid inserting cotton swabs, as they can push blockages deeper. If you experience pain, dizziness, or hearing loss, please have a doctor examine your ear.
