What are the characteristics of kidney pain with kidney stones?

The pain in the kidney area is usually characterised by the size and location of the stone, and is usually dull or colicky. In the case of large stones in the renal pelvis or calyces, there may be no obvious clinical symptoms or only a dull pain in the upper abdomen or lower back after activity.
If the kidney stone has caused a more serious infection in the kidney area, the main manifestation is a swelling or aching pain in the lower back.
