Back Pain
Renal colic or kidney stone pain is a severe form of pain. Many people often compare this condition with the pain when they are stabbed with knives or give birth. It is seriously intense and excruciating. You often feel it first when the stones move to the narrow ureter, which leads to a blockage and causes an accumulation of pressure in the urinary tract. The increased tension would activate nerve fibers and send pain signals to your brain. The pain usually shows up unexpectedly and changes in intensity or location when the stones move around. [2]
