Hello,
Painful lumps under the ear is commonly caused due to infection in the throat and neck like
pharyngitis,
swollen lymph nodes, swollen salivary glands, etc. Other medical conditions that can cause similar symptoms
mastoiditis, sebaceous cysts, lipoma, or life threatening tumors, etc. Get clinically examined by an ENT, get required blood tests, investigations and imaging tests done to detect the pathology so that treatment can be started at the earliest.
In the meantime, you should gargle your throat with warm salt water 2-3 times a day. Take
acetaminophen, one stat when needed. You can take a course of antibiotic like
Augmentin. Stay away from addictions and do not wet the ear, be very careful while taking bath or shower.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
