2. Migratory back pain
Migratory back pain Intense back pain is common in those who suffer from kidney stones, especially on the side and back, just below the ribs where the kidneys are located. The pain may also move down the abdomen to the groin and back, in waves of throbbing pain that fluctuate with sensitivity.
3. Blood in urine
The urine of people with kidney stones is often described as pink, red or brown. As these stones grow and block the urethra (in other words, as the pain gets worse), you will begin to notice a change in the color of your urine from light yellow to a “pink” red, a condition called hematuria.
