Please let me know greetings Edwin [/INST] Hello It is not necessary that pain in kidney area is always originating from that of kidney, this can also be associated with other conditions like muscle sprain, degenerative disease of lumber spine, fracture/ infection of lumber spine. Some conditions that cause pain are stone impaction in ureter, pyelonephritis, bleeding de to trauma, polycystic kidney disease, interstitial nephritis. You should undergo through some investigations like X ray USG of flank area, nuclear scan of kidney. Consult a surgeon for further evaluation. Thank you for consulting Chat Doctor. </s>
