The course of treatment is injections 0day, 3day, 7day, and 14day. I went to the emergency room to get these injections, at the recommendation of my primary doctor.
Unfortunately I don't have the bills anymore, but the total cost was a bit over $20,000, which insurance adjusted down to about $500/visit.
Basically, it would have bankrupted me if I didn't have insurance. Yes, the US healthcare system is really this broken.
