Blocked ear drops are mainly seen in the following situations: First, the drops, especially the oily ones, block the outer ear canal after they have been dropped. After blocking, it does not matter much. You can turn your head to the side and press for 5-10 minutes to play the therapeutic role of these drugs. You can tilt your head to one side and then let the medication flow out so that it will be clear, basically. Second, after the drops are applied, there may be cerumen or earwax in the external ear canal, which expands or becomes sticky after encountering the medication, blocking the surface of the eardrum and causing the feeling of ear blockage. You can clean the outer ear canal to remove the cerumen. Third, the disease itself, such as chronic tympanitis, acute tympanitis, congestion and edema of the eardrum, itself has a feeling of ear blockage.
