Frequent ear digging can lead to otitis externa, eczema of the external ear canal, and even tympanitis and thickening of the external ear canal wall. Frequent digging can damage the skin of the external ear canal, which can lead to inflammation of the external ear canal, such as pain, itching, and flowing water, etc. When accompanied by infection, there can be pus flowing from the external ear canal, and the pus flowing can stimulate the eardrum, leading to the occurrence of tympanitis. Repeated otitis externa can aggravate the thickening of the skin. Therefore, it is not advisable to dig the ear repeatedly at home by oneself, and not to dig the ear frequently to avoid damaging the skin of the external ear canal and causing the occurrence of the above-mentioned diseases. The skin of the external ear canal has the function of secretion of cerumen, which protects the skin of the external ear canal. When otitis externa occurs, it needs to be treated promptly to avoid further damage to the external ear canal.
