Now I feel the urge to urinate frequently even in day time although there is no pain while urinating.
Your symptom is called polyuria (excessive frequency of voiding). It can be due to many reasons which can be physiological or disease-related, and include excessive intake of liquids, diuretic substances (including tea, caffeine, alcohol, certain drugs), anxiety, exposure to cold, diabetes mellitus, diabetes insipidus (central or nephrogenic), urinary tract infections or obstruction, etc to name a few more common ones.
In your case, urinary tract infection should be ruled out by getting a complete urine examination and a urine culture done.
I hope it helps. Take care and regards.
Thank you doctor.
Just an update:
The issue went away by itself after a week or two.
