Hi welcome to Health care magic forum. Your daughter had bumps on legs and got relief with steriods. So these appears to be utricaria , they will appear again when the effect of steroid goes away. so they have appeared again. If the girl is rest less you can take her immediately to E.R.
Other wise there is no hurry. She needs some blood tests to confirm the diagnosis. They could be boils
, but they wont subside with only steroids
Besides i advise you some diet recommendations as Avoid taking brinjal, fish, and other sea foods, which tend to be potent allergens.
Wishing for a quick recovery and thanks for calling.
