If the patient has ear knots in the ear canal and does not remove them further, they may gradually proliferate and become larger, which may cause the ear canal to become completely blocked, causing the patient to experience stuffiness and discomfort in the ear, and may also cause a certain degree of hearing loss, or even tinnitus and other symptoms. Therefore, if the patient has already formed a mass of earwax or cerumen in the ear canal, which is difficult to be discharged smoothly on its own, it is necessary to go to the hospital in time for treatment. For smaller knots, they can be removed directly with tweezers or suction under light illumination. If the knot is large and hard and difficult to remove, you can use some phenol-glycerin ear drops or sodium bicarbonate solution to soften and dilute it before removing it further.
