[|Human|] Hi, I have a lump, smaller than a BB, under the skin on the shaft of my penis. It appeared a few days ago, and Im unsure if its bad or not. Ive looked all over the internet and many people have this, but I have not found ANY explanation whatsoever.
[|AI|]  Hi, thanks for the query to Chat Doctor. Dear, I understood your health concerns. Based on the facts of your query, your penile shaft lump could be, furuncle from hair follicle on the penile shaft, or could be from HPV pap pule. Both could be treated by medicines if needed. Nothing to worry about it. Consult Dermatologist if need be. Hope this reply would help you to plan further treatment in your case. Good Day!! Chat Doctor. S. Genl-CVTS
