Call the hospital, get the billing department ask if you can talk to someone about reducing the bill.
I had a similar situation once, said my chest hurt and everyone freaked out and I ended up with a 5k ER bill. With no actual answer to why my chest hurt, and was still hurting.
I talked to the hospital they set up an appointment with a woman, I showed bank statements, income, insurance information. Ultimately, because I had very little income or money at the time. They just forgave the entire amount. No more bill.
