Thanks for writing to us.
Though without clinically examining the area, it is difficult to confirm the diagnosis but it could be fungal infection
, neuro dermatitis or irritant dermatitis
. I would advise that you take oral cetirizine
twice in a day. Apply steroid
antifungal cream twice in a day. Also avoid cleaning the area with soap detergent,savlon or dettol as it can irritate the area.
If in case not much response is seen, please consult a doctor nearby for diagnosis and appropriate treatment.
