If the earwax in the ear canal needs to be removed, it is determined by the shape of the cerumen, as follows: 1. No need to remove: If the earwax is only scattered in the ear canal, there is generally no need to deliberately remove the earwax. The cerumen in the ear canal is difficult to be discharged smoothly and gradually accumulates into a mass, forming a cerumen mass embolism in the external ear canal, which can cause a more obvious blockage of the external ear canal and even further lead to a feeling of ear congestion, ear blockage, hearing loss, and even tinnitus, which requires further cleaning of the cerumen in the ear canal. If necessary, you can go to the hospital for cleaning, or you can use phenol and glycerin drops to soften and dilute the earwax.
