[|Human|] I have a round open sore on my penis shaft about the size of a pencil top eraser. It is painful when bumped. It also scabs and then when the scab comes off it looks sort of whitish. The sore is slightly raised around the edges but otherwise basically flat.I visited my doctor and he tested for a host of stds. All results were negative. He is suggesting that I may need to see a specialist. Meanwhile, I have been applying a triple antiobiotic ointment to encourage healing, but this does not seem to be helping any. The sore has existed for about a week now with no real healing.I will go see a specialist as suggested, but just to put my mind at ease, is there any idea what this may be?
[|AI|]  HelloThanks for query. You have ulcer over shaft of your penis since one week. You have not mentioned sexual history in your query.whether it occurred after unprotected sex ? You need to consult sexual disease specialist and get swab test and culture of a scrapping from the base of the ulcer to establish diagnosis. You need to take broad spectrum antibiotic like Cefuroxime along with anti-inflammatory Chat Doctor. Ensure to wash your genitals with warm water twice daily. Ensure to avoid sexual encounters till it heals up completely.
