I'm having to urinate frequently and i have to strain to push it all out every time i do. i finished medication for a uti a few weeks ago.

See answer: Your having to strain to urinate to empty associated with urinary frequency usually indicates that either your bladder is retaining urine OR your bladder is giving you the sensation of a full bladder with the urge to void when the amount of urine that is actually in your bladder is very small. Recommend seeing a Urologist who can help sort which of the above is occurring and the underlying cause.
