Help!

Hey mamas, I haven’t been on this app ever since my baby turned 1. However, I need y’all’s help. Yesterday she developed this rash throughout her whole body. It has been itching her, however, making her wear long sleeves top and bottom, she doesn’t scratch it but she does complain it’s itchy. I took her to her pediatrician and she said it’s something viral. She’s barley eating, even though her strep test came back negative. She said it isn’t hives or hand foot and mouth. She did develop a small low grade fever of 100.5 max, but that’s it. I really don’t know what it could be from and how to help her! Any advice or anyone have the same experience? Thanks mamas. 🤍
