What does this look like on my body?! Urgent!

Lillian

This is what it started out as about a week ago, I went to urgent care and they told me it was poison ivy and gave me a steroid shot and some medicine for 8 days. I’ve been on it for about 7 days, the second picture is what it looks like now.. Should I be worried/what does this even look like? I feel like it’s never going to go away :( it’s very dry and itches. It was also on my face which went away and on the side of my arm. Please help :( or is it healing? Last one is recent
