If possible send exact location of itch or pics. If you have fungal infection/itching, then home remedies or self treatment wont work to cure it, for fungal itch I will prescribe a schedule of anti fungal medication for your specific problem which have to be strictly followed or the fungii may develop resistance and come back later once cured.
Hence never self treat fungal itches with any self prescribed medicines or it may lead to resistance and lifelong problem. Do reply back for medication prescriptions. Being also a general physician
and registered dietitian, I prescribe both evidence based herbal as well as allopathic medicines complementing with dietary guidelines and home remedies carefully personalized for each individual patient.
