Hi dear user , thanks for using HCM service.
In order order to help you, I I will tell you the possible diagnoses for you.
First you need to know, that you have been treated with accurate medicines. However, there are some diagnosis which are out of the sexual relation context, that must be taken in count.
Those
pimples that turn with no skin like ulcer could be Simple
Herpes lesions. It is really common but to make finish diagnosis it is necessary to do a Tzanck test first. In a general way, It consist and take material from the lesions and look them at microscope.
I also recommend you to do do some test, like
VDRL, blood general test (hematology), and
glucose preparando all (before taking breakfast, at first hour in the morning) because high level of glucose in blood, can cause similar lesions in genitals. Then you could visit an urology specialist, to check if everything is Good. Or bring your labs results to this this website again to check them.
Hope to be helpful
Greetings
Dr. Nieves.
