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 of the red bump on back of your head-
Though not much information is there in the query,On the existing information it seems that you have-
Chronic Subacute Boil/Hairfollicle caused post combing trauma Or it could be
Sebaceous Cyst with combing
bruise and soreness/
Or could be
Epidermoid Cyst.Chronicity with soreness confirms it to be infective but needs to be ruled out from other causes of the
scalp lump.
Remedy-
Consult Surgeon for
Second opinion, who would treat it by investigation and clinical examination from many causes of such a scalp lump.
Anti-inflammatory / Antibiotics would reduce in few days time.
If not, Surgical Excision
Biopsy with HPR would treat it totally.
Don't Selftreat 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.
