Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. No, its not STD it is different candida infection. I suggest you to do microscopic examination once. This will establish and confirm diagnosis. Once the result is available you can be treated according to the results available. In most cases of candida infection clotrimazole vaginal pessary or fluconzole oral treatment can be taken. Please take the above medication under your doctors guidance. Please test yourself for blood sugar analysis. If you are having the high sugar levels than to control it is very important. If it will not remain in the control than it will recurr. Please maintain the good hygiene as it is the equally important tool as taking the treatment. I will be happy to answer your further concern you can contact me here or you can contact me on bit.ly/DrArun We wish you a best health at healthcare magic.
