new kitten ear tip curling

HELLO, Can anyone help me just got a kitten from my son's ex wife, It is actually my granddaughters, I wanted to take it for her , as her mother had to move back home with her mother. They took him to the vet 4 days before I got him to get him neutered, He came to me the end of last week with a little patch of thinning fur on back of left ear and it looked a little wet or something.  Now the tip of that ear is folding a tiny bit.  My son's ex said it was not there before, so could it be ringworm from the vet visit?   My sister volunteers (for about 20 years with forgotten cats) and has had SEVERAL, cat's in her care through the years, and has actually helped the vet out at times, and has learned alot about cat's. She said it sounds like ring worm from the vet visit, I have been using an anti fungal since yesterday., but to soon to really see if it improves . Has anyone ever had this happen, mostly concerned with tip of ear folding like that?

THANK YOU

Can you take a photo of it? That may help us

LOL I will see if my son can, I am SO not tech savvy it's really actually pathetic ! But I will try it kinda looks almost a brownish color, he is a orange tabby with orange and white on his ears.  So yeah Ill wait till my son is not busy.

THANKS

if it is ringworm i would wash everything thoroughly with a disinfectant that kills ringworm. isolate her so she don't infect others. wash your hands thoroughly each time you handle her. 

I will I just HOPE MY ZAZZY DOES NOT GET THIS!! As you can see by his picture he is a BEAUTIFUL CAT, FLAWLESS, his coat shines, he smells good , all of the time he is just perfect, I DO NOT WANT HIM FLAWED, Not to mention more so I don't want him in ANY discomfort, and I want him healthy My baby boy, the other cat is the kind that he is so funny looking he is cute actually adorable, zazzy is more of a regal Cat. LOL they are opposite as far as looks. Anyway , I don't want either one to have this .But I am applying an anti fungal in case I will keep you posted.

THANKS SO MUCH

only way to actually know it ringworm is take her a vet
