What causes a white color bump on the arm?
Patient: I had what looked like a oversized whitehead on the top top of my forearm(about the size of a pencil eraser. I did pop it yesterday and today the skin is very mushy and is draining clear liquid. It is a deep red color and kinda puffy. I am washing it with peroxide. It just doesn't seem to want to scab over. what should I do? Doctor: Hi,thanks for your query to my HCM clinic.I understand the concerns .In my opinion the white lump on the fore- arm-is a well ripe boil on the forearm with necrosed white head discharging after its bursting.Its not scabbing as the its not drained adequately.Hence You need Surgeons help , who would Incise and drain adequately, so that it would heal fast.So I would advise you to consult ER-Surgeon.Hope you would be relieved of your query. with this reply.I would love to help and Wellcome to HCM for more queries.
