Thanks for the query.
You are using a good lotion,
However it is necessary to use a mild steroid
cream to control the inflammation.
Also sitz bath or sitting in warm water with a pinch of salt will greatly help you.
Just do these simple things along with the lotion you are using.
Please meet a dermatologist
for final diagnosis and treatment
Let me know if you have any other doubt.
