hi,
I have read your question,
yes you have
fungal infection on the areas you have mentioned above.
Generally people suffering with
diabetes show such kind of infection commonly , in any case if you arent you can rule this out,
Maintaining hygiene in the pubic region is a necessity, since the problems sometimes increase to different levels , in your case you need not worry since it seems like in initial stages ,
I recommend you to apply anti-fungal ointment on the effected parts and the results may appear within 3-4 days , For itching use anti-
histamine tabs , and anti-inflammatory tabs to reduce the intensity of the infection.
If your problem persists I suggest you to consult a nearby
Dermatologist for further guidance.
Wishing you a good health,
DR.G.Gayatri devi.
