HI,Dear,Thanks for your query to HCM virtual Clinic.
I studied your query in all the details put forth by you.
I understood your health concerns painful sore hard bony post auricular lump on right side.
Cause about painful sore lump,which is hard immobile behind ear-
The facts of your query indicates that you have white
acne or
keratosis with white heads in the
scalp / or could be psoriatic white scales .
As the lump is noticed in last 2 hours with sore white head spots, White ancne / or Acne with blocked white sebum,due to hair
folliculitis of subacute type,seems to be the possibility in your case.
To rule out
Lupus would need Er dermatologists opinion,as I don't think it to be lupus.
Due to ambiguity in your complaints,to rule out if it could be normal mastoid bone also,
Second opinion from ER Surgeon is advisable in your case.
Hence I would definitely advise you to get Second Opinion from Er Surgeon
simultaneously,to avoid further complications of missed diagnosis.
So don't forget to take Second opinion from ER Surgeon .
Hope this reply would satisfy your query and would resolve the worry with it.
If you feel satisfied with this reply,don't forget to hit thanks and write excellent review comments,which would improve my rating for new needy visitors to HCM.
