What is when you think you have to urinate and don't?

When you think you have to urinate but don't, it may be due to a sensation known as urinary urgency. This feeling can be caused by various factors, including anxiety, overactive bladder, or irritation in the urinary tract. It can also occur if the bladder is not full enough to warrant urination. If this sensation is frequent or concerning, it may be advisable to consult a healthcare professional for evaluation.
