Hi there ~
I understand your concerns. It might be that you got the cure for the illness before getting the testing done and therefore the testing turned out negative for the illness - herpes
. It may also be that you may be having thrush
and the doctor gave you a treatment that was not correct and then used the right medication for thrush which is a common infection and is easily curable as well. I hope you keep the genital area clean and dry so as to avoid recurrence of thrush and also make sure that you practice safe sexual practices. I hope this helps and please consult a psychiatrist
as soon as possible.
I hope this helps. Take care and have a lovely day!
