The common causes of swelling below the ear include lymphadenitis, mumps, and folliculitis.
1. Lymphadenitis: when the local lymph nodes below the ear are inflamed, the local lymphatic reflux will also be impeded, resulting in enlarged lymph nodes, so the ears will be swollen below.
2. Folliculitis: If the folliculitis below the ear is caused by pathogen infection such as Staphylococcus aureus, the inflammatory cells stimulate the local capillary expansion, resulting in local redness, swelling and pain, which can cause localized swelling of the skin below the ear.
3. Mumps: The anatomical location of the parotid glands is in the maxillofacial area below the ears on both sides, and if mumps virus infects and produces mumps, the neighboring area will have symptoms such as swelling, pain and elevated skin temperature. That’s why you can get swollen underneath your ears.
There may be other reasons for the swelling below the ears, it is recommended to go to the hospital in time to complete the examination, to clarify the cause of the disease to give targeted treatment or treatment.
