Ear picking is generally more common in foot massage parlors, or regional centers. This kind of ear picking is generally bad and is not recommended in these places. This is because the tools in these places are used repeatedly, without formal, sterile disinfection, which can easily cause cross-infection. Especially for patients with mycotic otitis externa, it is easy to cause cross-infection in such cases, which can lead to mycotic otitis externa. Repeated ear digging and ear pulling is also not recommended at home during normal times. This is because repeated ear digging can easily stimulate the outer ear canal wall and cause chronic otitis externa. If there is pus, water or pain in the external ear canal, it is generally recommended to go to the hospital and clean it up with professional instruments.
