Ear pain is mainly caused by otitis media, herpes in the ear, and ear wax. 1. Otitis media. This condition is caused by bacterial infection, which not only causes a stinging sensation, but also leads to pus flowing from the ear. Generally, this condition occurs at night, and pus flows out of the ear when the patient sleeps. For this situation, you need to seek immediate medical attention and have your ears cleaned so that the pus does not block your ears. 2. Ear wax. The excrement in the ear is earwax, if not cleaned in time, when the earwax increases to a certain amount in the ear to form hard lumps in the ear directly stimulate the wall of the ear canal causing pain, while causing hearing loss, once the earwax is wet by water will also induce other ear diseases. 3. Ear herpes. This is one of the more common causes of ear tingling, which is caused by viral invasion and infection and can cause a tingling and burning sensation in the ear. Don’t take the tingling in your ears too lightly. If it happens often and lasts for a long time, you should always go to an ear doctor to have it checked to prevent any pathology.
