Diaper rash help!

Myia

Hey mamas, so my daughter woke up with really bad diaper rash! It's super red, she cries when I try to change her diaper or wipe, she's pulling at her diaper & now shes having a hard time falling asleep. What should I do!? Take her to her pediatrician? She's never had this bad of diaper rash before. Were also in an apartment with 95% carpet so I can't necessarily let her walk around without a diaper on!
