Thanks for your query. Based on the facts that you have posted it appears that you have developed infection of the glans penis
Please note that any injury
or spots that develop on glans do not heal up with scar tissue. One thing I can assure you hat this is not due to scarring over a glans.
Please take antibiotics for 2 weeks along with topical antibiotic
