<human>: Can you give me the gist of the text in a nutshell?

This past Saturday I went to the ER for a pain in my lower back/abdomen. After doing blood work, a urinalysis, and a CT scan the doctor told me it was a kidney stone and gave me some anti-nausea and pain meds. The nurse told me to come back if I got a high fever.

I don't have a fever, but the pain hasn't really gone away and I'm still getting nauseous/vomiting. I don't know how long the pain from this kind of thing can last and I'm hoping someone who has experience with this kind of thing can tell me if I should go back to see a doctor. 

I'm an American with no health insurance so I don't want to rush back in to see someone if it's normal. I shudder to think what the original ER bill is going to be. 

I fully understand that this is not a substitute for medical advice, only a personal suggestion.
<bot>: I was diagnosed with a kidney stone on Saturday. The pain hasn't gone away. Is this normal or should I go back?
