Did anyone's LO get a rash all over their body while teething?

R had a nasty, red, pimply rash pop up on her face, arms, belly, and legs yesterday. Her temperature was 100.1 at the pediatrician's office. The pediatrician said she thought it was a virus but my mom and my MIL said my husband and I got rashes when we teethed. The rash and higher temperature went away overnight but now they're both back.
