In life, if a patient always has pimples in the external ear canal, the following reasons are mainly considered: the first and most common is that the human body’s sebaceous glands are highly secreted and easily blocked, so it is especially easy to cause pimples in the external ear canal, mostly seen in patients with oily skin. The second one is mainly due to inflammatory stimulation. Patients may often use their fingers or cotton swabs to pick their ears or dig their ear canals, which can easily lead to inflammation of the mucous membrane of the ear canal, resulting in the formation of many small inflammatory pimples, sometimes with obvious pain, and when the infection is present, it may even break out and flow pus, causing certain problems for patients. Regardless of which of the above causes is responsible, patients are advised to actively deal with the situation to alleviate their ear discomfort and, if necessary, go to the hospital for further examination.
