[|Human|] I have back pain in my lower left side, came on suddenly on the tennis court. I thought it was a muscle but advil did nothing for it Some one said it could be my kidneys. If its a strain, I ll rest, if it s my kidneys I should see a doctor. How can I tell for sure what it is?
[|AI|]  Hi, Welcome to Chat Doctor. Looking to your query it is likely that to be muscular pain. Treatment of it is analgesic (diclofenac 50 mg)three times a day ALONG WITH OMEPRAZOLE 20MG DAILY. If this pain is spasmodic and radiating towards abdominal anteriorly, or you are having problem in urine then it can be pain due to kidney. It will require ultrasound abdomen to rule out it. Hope my answer will be helpful to you.
