Infection
An infection in the kidney or bladder can cause muscle groups around these areas to spasm suddenly. These contracting or squeezing feelings are natural responses of the body to the irritation caused by viruses or bacteria. Fortunately, these problems are just temporary. All of the issues with your bladder control will improve over time when the infection is treated properly. So, if you have some typical symptoms of a kidney or bladder infection, keep in mind to seek immediate medical treatments to prevent further complications. [4]
