I had a liver biopsy at 10:00am on 2/24, went to the ER on 2/25 due to a fever, chills, and the worst pain I have ever experienced. The ER performed ultras sound, x-rays, CT, blood work, and a physical exam and all came back negative and no bleeding. Its 2/27 and I am in sever pain and still can t breathe normally. The ER discharge notes said go see my doctor and my doctor is saying go to the ER for pain management. What is causing this pain? Any help you can provide would be greatly appreciated.
