Welcome to healthcare magic
What you could be having might be ring worm
. I recommend you to stop hydrocortisone cream
as it is not good for ring worm. You may try an over the counter antifungal cream like miconazole
2% twice a day for two to three weeks. In spite of this if rash
is not coming down, I will recommend you to see a doctor.
Keep the area dry.
Hope this helped
