Thank you for posting your query at DoctorSpring.com
I can understand your concern.
This seems to be candidial intertrigo, which is a yeast infection caused more often due to conditions of heat and humidity.
It doesn't seem to be a std right now.
Application of clotrimazole cream twice a day would be helpful.
Please let me know if you have any queries.
Patient replied :
Are the symptoms congruous with the std Chancroid? My sexual activity was with a sex worker in Mexico.
Thanks for your reply.
It doesn't look like chancroid at present atleast.
It looks like a candidial intertrigo.
