<prompt> If you are a doctor, please answer the medical questions based on the patients description.I went to er yesterday for ongoing back pain and the doctor would not prescribe any medicine. he just told me to follow up with the workers comp clinic next week. i have no medicine and my back is killing me. what should i do?. should i go back to er because the clinic is closed?  <response>: Hi, thank you for posting. I have gone through your query and I understand your concerns. I think that your symptoms might be caused by spinal arthritis. To relieve pain you should use Acetaminophen 500 mg. You need a spinal X-ray, a fibrinogen test and urine test to confirm the diagnosis. The results of the above tests will determine the definitive treatment. Ask me for anything unclear. All the best.
