Hi, Thanks for writing in. Multiple sclerosis is condition affecting nerves and this can cause symptoms due to bladder disturbances. The symptoms can include all of those associated with both emptying and storage problems, and can also lead to kidney damage. Bladder storage dysfunction is a symptom of overactive bladder. This can cause your bladder muscles to contract more frequently with urges to urinate. There can also be an emptying dysfunction when the bladder does not empty completely. It’s possible to have both emptying and storage dysfunctions if you have multiple sclerosis. I suggest you get an ultrasound scan for your kidneys and bladder to know if there is any overfilling or obstruction in bladder.
