[|Human|] Trying to decide if I need to go to the emergency room. I am a 59 year old female. About 1 hour ago, all of a sudden, I started having severe pain in my lower back toward the front on my right side. Also started having chills and feeling nauseated but not vomitting. I had a kidney stone 8/12 and this is so similar to that time.  I still had some pain pills from before so I took one and I am sitting on a heating pad. I am not passing blood and currently I do not have the frequency to urinate that I had before.
[|AI|]  Hello Fairbanks for your query at Chat Doctor. Severe pain in right side, nausea, chills and previous history of stone suggest that it could be recurrence of stone in kidney (nephrolithiasis). Pain in nephrolithiasis is very severe with nausea, vomiting. Pain can persist up to 4 to 18 hours duration. My recommendation for you is to consult urologist get investigation like ultrasound abdomen and discuss with him for further investigation and management. For temporary relief of pain till you visit doctor tablet acetaminophen can help. Regards.
