Hi,
It seems that you are having
fungal infection.
It may be
tinea cruris or candidal intertrigo.
Perspiration,soap,excessive use of water, fitting clothes..etc may exacerbate the disease.
In both cases, antifungal drugs like
ketoconazole,itraconzole or fluconazole with antihistaminics would be helpful.
Antifungal cream will reduce the infection.
Avoid soap bath, you may use dettol liquid for bath.
Improve immunity with immunobusters.
Blood tests shoud be done to rule out DM,HIV,anaemia or other internal diseases.
Avoid stress, worries and anxiety.
Have healthy food and proper sleep.
You will be having good results.
Still, you may
consult dermatologist.
I hope you got my answer.
Thanks.
Dr. Ilyas Patel MD
