Thank you for the picture.
It is hard for me to tell from the pictures and data you provided if this is chicken pox or mumps.
In either event they are both caused by a virus and there is no treatment.
If, however, the swelling of her glands is from secondary bacterial infection then antibiotics may help....
So. What should you do?
I would take your daughter to the pediatrician in the morning for an exam.
Does she need to go to Emergency?
From what you have posted, I do not believe she needs to at this time. But, if you are concerned then it is not unreasonable to do so.
Does this make sense to you?
