<human>: During MMA practice I landed hard on the lower left side of my back. 6 hours later I was doing a cardio workout and felt pain deep inside on that lower left area of my back. Nothing horrible but it did interfere with my workout. Could this be my kidney?
<bot>: Hello and welcome to Chat Doctor. As a Urologist, i can understand your concern.It's unlikely to be due to, injury to the kidney. The kidney is well protected by the rib cage. However after an examination by a doctor, you should get a scan done. Get an ultrasound or CT scan of the abdomen. This will give an accurate idea, of the cause of pain. If you've any doubt, send the report, as a direct question. Chat Doctor.  Manga.
