Whether having urinary stones can be painful depends on the specific case of stones. Urinary stones, also known as urinary stones, can be divided into kidney stones, ureteral stones, bladder stones and urethral stones depending on the location of the stones. The main symptoms of stones are pain and hematuria, but different parts of the stone behave differently. In the case of kidney stones, the pain is not very noticeable, and especially larger stones are not too painful, often manifesting as a swelling and pain in the kidney area. Some small kidney stones may have significant pain. Chinese medicine says that if a stone does not pass, it will be painful. Small stones blocking the exit of the renal pelvis or the renal calyces will have significant pain and renal colic. Ureteral stones are painful and noticeable, and the pain is more common and very intense. Because ureteral stones are often blocked in the ureter, poor drainage of urine will cause renal colic. Bladder stones are less painful, and when urethral stones become obstructed, they will also cause pain in the urethra.
