Insurance hospital help question!

My son (age 9month) dropped top ramen on himself! I was at work my sister was "taking care of him" and I came home to news that my son tried to reach for the soup right when it was taken out of the microwave and it dropped all over his poor face/arms/hand/legs. I took him to the hospital since he literally was crying like he was in pain and nothing they tried putting on him would calm him down. Anyways I took him to the hospital and they said they couldn't do anything about it because he has no insurance!!!? I'm beyond pist! He literally has the worst burns! They look like bad 3rd degree burns. He's still crying in pain 😥😥😢 why would the hospital not help my poor child! Just because he has no insurance! Can they do this????? All they said was to buy him a sort of cream! But didn't take him in or anything 😢😥😥
