The most common causes of CKD do not cause any pain. And, much of the pain that is near the kidneys is not caused by a kidney problem. But some people who have CKD do have pain. Some people with kidney problems may have pain in the upper back (where the kidneys are) or on the same side as the affected kidney.he most common causes of CKD do not cause any pain.

Diuretics are used to treat disorders such as hypertension and several types of edema that are caused by conditions such as heart failure and cirrhosis of the liver. However, use of diuretics can lead to complications, including dehydration and electrolyte imbalances. The action of carbonic anhydrase inhibitors reduces the rate of hydrogen ion secretion and there reabsorption of bicarbonate ions. The bicarbonate ions increase tubular osmotic pressure, causing osmotic diuresis. With long-term use, the diuretic effects of carbonic anhydrase inhibitors tends to be lost.
water reabsorption will cause the concentration of the solute to rise to a point at which further water. reabsorption is prevented. This is the mechanism by which osmotic diuretics act (see below). Organic acid secretory systems are located in the middle third of the proximal tubule (S2 segment). These systems secrete a variety of organic acids (uric acid, nonsteroidal anti-inflammatory drugs NSAIDs, diuretics, antibiotics, etc) into the luminal fluid from the blood. These systems thus help deliver diuretics to the luminal side of the tubule, where most of them act. Organic base secretory systems (creatinine, choline, etc) are also present, in the early (S1) and middle (S2) segments of the proximal tubule. Loop of Henle
