A 12mm
kidney stone was seen on a CT scan on 8/4/17. I haven't really had any issues with it, but for the last 3 days I have had constant back pain. The pain gets worse when I eat or drink anything. I tried to take ibuprofen (thinking it was just muscle pain) and that worsened the pain. Last week I was nauseous and vomited for three days. I am still nauseous but have not vomited since 9/6/17. At what point do I go to a doctor or the ER? Is the ER the best option?
