That feeling is very common and usually comes from irritation or your bladder not fully relaxing or emptying. It can be harmless, but sometimes it signals an infection or another urinary issue.
Common harmless reasons
Sometimes the bladder and the nerves that signal “I have to pee” stay a bit active even after you actually emptied, so you still feel an urge even though there is very little urine left. This can also happen if you recently drank a lot of fluids or things that irritate the bladder, like caffeine, alcohol, carbonated drinks, or acidic foods.
Possible medical causes
Frequent urges right after peeing can be a sign of a urinary tract infection, especially if you also have burning, pain, cloudy or bloody urine, or fever. Other causes include overactive bladder, bladder irritation (like interstitial cystitis), or, in some people, pelvic floor muscle problems that make it hard to fully relax and empty.
When to see a doctor
You should get checked soon if the feeling is new, keeps happening, or comes with burning, pain, blood in your urine, fever, back pain, or trouble starting or stopping your stream. A clinician can test your urine, look for infection or other issues, and suggest treatment or pelvic floor therapy if needed.
Simple things to try
Until you can see someone, it may help to drink enough water but avoid bladder irritants like coffee, energy drinks, alcohol, very acidic juices, and fizzy drinks for a few days to see if it eases. Try taking a bit more time on the toilet, relaxing your belly and pelvic muscles and waiting a few extra seconds after you think you are done, which can help the bladder empty more completely in some people.
