my bladder is full but can't pee

Hello. Thank you for posting.

Some causes of urinary retention include an obstruction in the urinary tract such as infection, an enlarged prostate (men) or bladder stones, that cause swelling or irritation, nerve problems that interfere with signals between the brain and the bladder, medications, constipation, urethral stricture, or a weak bladder muscle.

See your doctor for an evaluation.
