Please "make" him go back to the ER, this is not something to mess with. He appears he has internal injury's and the thought of getting Medicaid is a good one but could take weeks or months to get it to go through.....that is weeks and months he does not have.
I do understand his fear of the money, but what could is not being in debt for a medical expense if his life and health are at stake.
I will be praying for both of you, I can only imagine how terrifying this must be to see your son so sick.
