Kidneys have NO pain receptors...
Probably back muscles.
Para spinals: iliocostalis, longissimus or semispinalis.
kindeys can cause pain when stretched out or other reasons
Kidney Stones
Cause of Pain: The pain caused by kidney stones occurs when a stone becomes lodged in the ureter, the slender tube that connects the kidney with the bladder. Urine flow is then blocked, which causes urine to back up into the kidney. The kidney then swells and enlarges,
stretching the pain-sensitive capsule, or thin covering around it.
What to expect: The pain caused by kidney stones is referred to as "colic," meaning that it comes on in waves as opposed to being a steady continuous pain. Pain from kidney stones is described as being almost as severe as that of childbirth. Patients with renal colic usually find it very difficult to hold still, and are in constant motion, pacing and writhing. Often the pain is so severe that it causes nausea and vomiting.
Although the pain starts in the right or left flank area, it may move as the stone travels down the ureter. The pain may move around the side of the trunk to the lower part of the abdomen in the front and even travel down to the groin.
Kidney Infection (also known as pyelonephritis)
Cause of Pain: Pain caused by kidney infection (pyelonephritis) is related to infection and inflammation within the kidney tissue. Infection causes the
kidney to swell, and stretches the pain-sensitive capsule surrounding the kidney, leading to a sharp, aching pain.
What to expect:
Patients with kidney infection are very sensitive to even the lightest touch in the flank area. They are usually quite ill with the infection, and generally have high fever, nausea, and vomiting as well. Infection of the kidney is much more serious than the much more common condition of bladder infection. Pyelonephritis needs to be treated promptly with intravenous antibiotics in order to prevent spread of infection to the bloodstream
just think you might be wrong thats all.
