Hello and hope you are doing well.
The swollen and red eye might be due to conjunctivitis which is inflammation of the thin transparent membrane which covers the eyes. Fever may be caused by a cold, which often happens along with viral conjunctivitis, but sometimes fever is a sign of a more serious infection of the eye or other part of the body. Also, swollen eyes can occur with other inflammations or infections of other parts of the eye like iris, cornea, lens etc. It's important that an element of injury needs to be ruled out so you will need to consult your primary care physician for further evaluation.
Hope this helped and do keep us posted.
Hi, I would have her seen by her Ped to be certain it isn't getting infected. You may have one or two things going on but with a temp for 3 days I would go for a look/see.
Please let us know how she does.
