Thanks for the query,
You might be suffering from fungal infection
But the medication might not be working on you.
There can be two reasons.
First is that the fungus is resistant to the drug used by you.
Second, you might have used the medication for short period.
Any anti fungal cream must be applied for at least a month.
Please meet a dermatologist
for final diagnosis and treatment
Let me know if you have any other doubt.
