ya- she should see a doctor, pronto...
medical advice is best served from the pros-
and it sounds like she may need a dose of anitbiotics if she is fighting a fever and infecton...don't mess around, just go.
her rigs or tracks may have let something in, ya know?
get it checked out.
let us know how it goes.
as for short term-just cool cloths to her head and the back of her neck, especially...but only for her comfort on the way to see a doc.
i wouldn't suggest anything that might not benefit her, ya know?
