My guinea pig has a hairless spot on her nose. Should I be worried?

My guinea pig has a hairless spot around her nose. When I bought her from the store there was a white ball on her nose and it eventually fell off after I started taking care of her. The spot seems like it might have grown some hair back but I’m not entirely sure and I’m a little worried.

Hello. Thank you for using PetCoach! This looks like a ringworm lesion to me. http://www.peteducation.com/article.cfm?c=18+1800&aid=2494 You can try using a topical anti-fungal medication like Clotrimazole to see if it helps. Apply a thin layer to the lesion twice a day. https://www.walmart.com/ip/Antifungal-1-Clotrimazole-USP-Cream-1-oz-tube/950932820 Remember two important things: 1. It can take weeks to months for ringworm to resolve. If you are not making much progress with the cream after a couple weeks I would take her to the vet. They can give you an oral medication to use that may be more effective. 2. Ringworm can be contagious to people so wash your hands thoroughly after handling her. Hope this helps. Best wishes.
