It hurts to pull out the tympanic membrane from the ear. Clinically, there may be the following reasons: First, the patient broke the tympanic membrane when pulling out, causing the remnants of the tympanic membrane to be pulled out. This is still rare clinically, because the tympanic membrane is deep in the ear canal, and it is not easy for the patient to pull out the tympanic membrane by himself, because the part of the ear canal close to the tympanic membrane is very narrow and the pain is very obvious, and most patients, because of Most patients stop pulling out their ears because of the pain and shrink their hands. In this case, it is necessary to go to the hospital immediately to have the eardrum checked by a doctor, and anti-inflammatory treatment is needed to see if the perforated area of the eardrum can heal within two months. Secondly, when the patient pulls out the ear canal, it causes damage to the skin of the ear canal wall, resulting in a skin defect, which is still found clinically and results in more bleeding from the ear canal and very obvious pain. Thirdly, some patients pull out pieces of cerumen from the ear canal, and these pieces of cerumen may be in the form of large pieces, and the patient thinks it is the eardrum, but this condition is generally not the eardrum.
