Hello and welcome to HCM.
I understand your concern.
It is less likely to be
HIV as you don't have any other health complaint.So you need not worry on that aspect.
It seems that you have
genital candidiasis also called as
thrush as you mentioned.
If I were your treating doctor,I would recommend
---local application of
fluconazole containing ointment
-one 150 mg tablet of fluconazole weekly for 6 months,but since this is a prescription tablet,you need to get a physician 's prescription for it.
-use condom while having sexual intercourse
-maintain hygiene,wear clean and dry undergarments and avoid using synthetic material inner wears
-simultaneous treatment of your partner is also important,since this infection can be transmitted sexually.
If still there is no improvement after this steps,certain investigations need to be done like blood tests,urethral discharge tests to rule out the causative infecting organism.
Hope this helps.
Thanks.
