So I believe Mya has a ringworm

I just noticed it about an hour ago. I have her quarantined in her play pen. She is crying and although I feel soo bad, I know I cant let her out

I am aware that it is contagious. I am going to take her to the Vet in about 2 hours. Hopefully I am wrong and its not a ring worm.
I heard Lotrimin is suppose to work well for both humans and pets? Has anyone had success with it?
I just wanted any advice that you guys could give me. I would greatly appreciate it. Anything from home remedies, your personal experience, how to clean the house, pretty much anything that could help out. Thank you.
