What can I do

My two year old had dental surgery yesterday. Today, she has a fever and she doesn’t want to take any medicine and I don’t want to hurt her mouth trying to get her to take it, I’ve tried mixing it with water and she didn’t want to drink it and she hasn’t been wanting to drink juice so I can’t mix it with that. What else can I do to bring her fever down. All she wants to do is be in bed so I can’t give her a bath either. Taking her to the ER would be my last resort because they usually just tell me to give her medicine and I also tested positive for COVID so I can’t go out.
