Hello,
Welcome to healthcaremagic.com
I have read your query in detail and can well understand your concern.
You are most probably suffering from a
fungal infection.
Remember to wear loose cotton clothing specially when at home.
Avoid hot humid climate, keep the affected area dry and avoid synthetic innerwear..
Do not use any over-the-counter medication like neoclobenate over this area as it will only increase the problem and may also result in secondary infection.
Antifungal medicine, both oral and topical medicine for 1-2 months will completely cure you of this disease
However, to confirm the diagnosis, You should get a KOH examination of skin done.
Or you can put up a picture of the affected area for clinical diagnosis.
Hope this helps.
You can revert back if you have any further query.
good luck!
