Hi there Young lady.
I read your detailed history & clinical description with interest.
At the outset, when you say there was a test for the basic STD's are we to presume that herpes
was not included?
If so, please get a Herpes IgG & IGM serum test done at the outset. This will help give you a clear idea if indeed it is Herpes infection & if so, it will also tell you if the infection is of recent or old origins.
It is very likely that it is a simple fungal infection
or a mixed bacterial/fungal infection & /or a fixed drug eruption
. These are fairly common differential diagnoses.
Prayer is useful but will not take away from the practicality of having to treat said infection or allergy
. Wish you all the best. Please do get back to us on the premier portal usiing the 'ask-a-doctor' icon with your test results & will be happy to help sort you out.
Cheers & Godspeed!
