That sound a lot like strep. We have recently had it in our family and my in-laws get it a lot too so I am somewhat familar with it. I would take her to a clinic tomorrow and have it checked. With strep, the sooner you catch it the better and once she has been on antiboitics for 24 hours she should be ok. If it is not strep, at least you will have a better idea of what you are dealing with. If you can't get into your doctor, you can always take her to Walgreens or CVS clinics. We do this all the time and they are MUCH better then urgent care. They will bill your insurance just like your doctor.
