Hello and welcome to HCM,
The bumps at both the sites that is scalp
and the ear lobe can be due to skin and sot tissue swellings similar to boils
. Or they can be swellings which we call the sebacious cysts which are common in these areas.
In any case wait for the pain to subside and if the swelling does not disappear with routine antibiotic medication (both oral and topica) then consult an ENT who will in all probability suggest a biopsy
to confirm the diagnosis and it will be a permanent cure. The biopsy is a small procedure and can be done in local anesthesia
and in will usually not even require an admission.
