Having severe pain in my right side but ct scan and bloodwork came back normal?

I’ve had pain for 10 days in my right side getting more intense and frequent. I ended up in the ER yesterday bc the pain got to the point that I was shaking and nauseous. Immediately they suspected kidney stones and when it was ruled out from the bloodwork and CT scan, they sent me home with a prescription of painkillers and anti-nausea medicine and told me to FU with my Dr. So, here I am, still in the same pain, even with the pain medicine, which is now radiating up my right shoulder, and across my midback. What should I do?!
