i would say yes seek immediate medical attention. obviously it's impossible to diagnose the situation in a forum like this but your daughter could be experiencing an allergic reaction. this should be addressed as soon as possible. i hope everything turns out ok!
daughter has the flu sinusitus and now has a red rash all over her body eyes swollen and yellow underneath. er? . she has a fever again still taking her antibiotics and tylenol 3 for pain.
