Hi,Dear Thanks for the query to HCM virtual Clinic.
I studied your query with available details given in your query.
I understood your health concerns.
Cause for the post-auricular lump-
From the limited facts and story of your query, you seem to have infective lump , and mostly it is
Lymphadenitis with infection of the
Scalp.
A
Treatment-Would depend on the cause.As I don't have any first hand clinical information, I would suggest to consult ER Surgeon to rule out other causes and who would treat it accordingly by either medicines or by surgical excision if need be.
Don't Self-treat or medicate in your case as the case may go in to further complications.
Hope this reply would resolve your query and would help you to plan treatment with your doctor.
Hope this would relieve of your health concerns.
Welcome for any further query in this regard before final suggestions are given in your query.
Wishing you fast recovery..
Have a good day.
