Used Lotrimin To Cure Jock Itch. Noticed Small Ulcer On Foreskin Below Penis Head. Worrisome
Thanks for your query.
Based on the facts and photograph that you have posted, you had a ringworm infection in groin and genitals very recently and have developed two small ulcers at coronal sulcus.
Mostly this could be due to acquired secondary infection probably due to scratching
In absence of any unprotected sex and any sexual relation with other partners and other symptoms of UTI, there are no chances of any STD at all. Please take some antibiotics like Doxycycline under the supervision of your doctor for couple of days along with topical antibiotic ointment like Neosporin over ulcer. Observe good personal hygiene and hopefully this should get cured in a week .
Hope I have answered your query .Please feel free to ask if you have any more questions I shall be happy to help you.
Regards.
