Welcome to Just Answer. I'm Dr. Gregg and I will try to help you today.
How old is the pig? Is she alone? What is her diet?
She is 4 years old I think I have only had her a couple of months. She is alone and eats guinea pig food and fresh veggies.
From your description I suspect she has a serious bacterial infection and needs antibiotic therapy asap
do i get them?
You will need to find a vet who treats guinea pigs for proper treatment
You are welcome. I hope this works out well for cupcake. I have raised lots of GP,s and know how attached you can get to them
