You have been experiencing pain in your left abdomen and have undergone treatment for pyelonephritis. An imaging scan showed that a small renal cyst slightly off the cortex in the kidney is the possible cause of some of your symptoms. Briefly, such cysts are usually benign and do not require treatment unless they grow or cause symptoms. In your situation, please continue to receive the necessary treatment for the infection, and they will also check the cyst to be sure it is not causing any inconvenience. 

Kidney stones might develop on one side of the body or both. They are similar to small stones that grow in a person's kidney. Signs include urine containing blood, having a problem urinating, and pain in the back or side. Causes may result from not drinking enough water and eating too much salt. To cure this condition, one may need to take a lot of fluid or use particular drugs; in some cases, an operation might be necessary to remove the stones.

Kidneys filte­r waste from blood. If creatinine le­vels rise, kidneys struggle­. Tiredness, swelling, and nause­a occur. Causes include hyperte­nsion, diabetes, certain me­dications. Doctors prescribe medicine­, diet changes, sometime­s dialysis. Following medical advice prese­rves kidney function.

The function of the kidneys worsens when you eat large amounts of protein, and the kidney problems become more severe. The extremely high rates of creatine supplements can make the kidneys unable to function properly. Before you start any regimen, consult with your doctor to figure out the best approach that is right for your body.
