Ear bone pain is not necessarily due to fire. Clinically, ear bone pain is mainly classified into the following diseases: First, cartilage pain in the auricle, commonly induced by purulent chondromalacia, mainly due to the invasion of cartilage and cartilage membrane by the lesion, resulting in localized purulent formation of infection, leading to pain in the cartilage. Secondly, acute otitis externa may be related to fire. Some patients, for example, get fire, stay up late, eat spicy and stimulating food, which leads to local infection under the ear canal. If the pain is very pronounced in the case of an ear canal boil, it is mainly due to local swelling after which the nerve below the ear is compressed and nerve pain occurs, which also manifests as a painful sensation in the ear canal. Third, pain in the mastoid bone behind the ear is common with inflammation of the lymph nodes behind the ear, and in some patients who have middle ear mastoiditis, for example, painful pressure on the mastoid area is also possible. In conclusion, pain in the bones of the ear is not necessarily a result of fire, but is often caused by infection.
