Inflammation is a common cause.
One of the most common causes of sudden ear pain is possible inflammation. For example, otitis media can directly cause ear pain, or it may be pain around the ear caused by inflammation in throat and other parts. If it is otitis media, the acute symptoms are dull pain or throbbing, while chronic infection will oppress the tympanic membrane and cause intermittent pain. At this time, you need to go to the hospital to check and make sure, and then ask the doctor to prescribe some anti-inflammatory drugs or ear drops. Don't treat them separately. Generally, otitis media is mostly caused by a cold and also has symptoms of fever.
Otitis externa caused by improper ear digging
Another reason is otitis externa, which is also very common. The reason is that many people like to dig their ears and use tools improperly, such as nails or small sticks. If they dig hard, they will understand that they itch and easily hurt the ear canal. If damaged, it will cause inflammation and other conditions, leading to ear pain. If it is not serious, you can apply some anti-inflammatory ointment or anti-inflammatory ear drops yourself, and try to avoid violent ear digging in the future.
Other reasons
In addition, herpes around the ears can also cause pain, usually caused by viral infection, and it is usually more painful than the previous ones, and occasionally accompanied by symptoms such as nausea and vomiting, which requires going to the hospital for medication. Others, such as auricular neuralgia, are pain caused by noise stimulation, which is not serious and does not need treatment. There is also earache caused by nasal cavity problems similar to colds, which will be relieved or disappeared with the treatment of colds.
The above introduces some causes of ear pain. Either way, if you feel serious, you'd better go to the hospital for treatment so as not to delay your illness.
