Woke up nauseaous, vomited about five times, and the last one included blood so I went to the emergency room. I spoke to a doctor for less than five minutes and received no imaging. There was one routine blood draw and an IV with saline and Zofran.
God damn America. $3042 to walk in the door. I could have literally flown back to England and been seen at an NHS hospital for a 5th of the cost.
I think if they get you on record admitting to the debt, they can sue you in court for it. so best practice is to never answer their calls, even if it's to say fuck off.
