What Causes Bladder Spasms?

Bladder spasms can be best described as the action of the bladder contracting or squeezing involuntarily, which sometimes causes the affected individual to urinate when they do not intend to. The sensation of a bladder spasm is one that happens suddenly or without any warning. Bladder spasms cause a burning sensation and or cramping pain. Other symptoms of frequent bladder spasms include accidental urine leakage, waking up several times a night to urinate, and frequent urges to urinate. The symptoms of bladder spasms tend to simulate those of a urinary tract infection.
