Have A Large, Hard Knot Behind Ear Directly On Mastoid Bone And Fever. Concerned
Thanks for posting your query.
A large hard painful knot behind your ear could be a swollen lymph node or an infection like abscess or an infected sebaceous gland.
For the confirmation of diagnosis, you need to get this lump examined from a doctor and get a MRI scan for any soft tissue growth and a FNAB (fine needle aspiration biopsy) done.
Till then, you get this lump examined from a doctor, apply warm compresses on the lump because if it is a swollen lymph node or boil then application of warm compresses will help.
You will need systemic antibiotics and anti inflammatory drugs to take care of the infection.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
Dr. Praveen Tayal.
