I ve been experiencing back and abdominal pain, nausea and vomiting and a slight fever. I have a history of kidney stones so I thought maybe one was stuck, but I went to my urologist today and he couldn t see anything on an xray. He told me to have a CT scan and come back in 2 weeks. Meanwhile, I m still in pain,, still vomiting and still nauseous. Any ideas would be appreciated.
