Heat Pack
A warm cloth or heat pad applied to your abdomen, flank, or back can help minimize your kidney pain. The heat would improve your blood flow and reduce nerve sensations, both of which can alleviate pain. This option is especially useful when your pain is triggered by a muscle spasm. Keep in mind that heat packs cannot cure your underlying cause but can only make you feel more comfortable. Similarly, you can also soak in a hot shower or bath in around 20 minutes. Avoid applying too much heat as it would cause burns. [6]
