Thank you for all the information,
There can be a few possibilities.
It can be from allergy or dermatitis.
OTC Hydrocortisone cream can help allergy.
You can try Hydrocortisone first.
A yeast infection is also common here as you had before.
Lamisil cream is used in yeast infection.
If you do not see improvement, I would suggest to take an examination by doctor.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
