If you have frequent urination and pain during urination, it suggests the presence of urinary tract infection or urinary tract stones, it is recommended to go to the hospital for further examination to clarify the specific causes. 1. When acute urinary tract infection occurs, the mucosa of the urinary tract can become congested and edematous, with increased sensitivity, and a small amount of stored urine can produce a strong desire to urinate, so the symptoms of frequent urination can occur. When urine flows through the congested and edematous mucosa of the urinary tract, it can produce irritating pain, so painful urination can occur. 2. Painful urination, or hematuria in the naked eye and other symptoms, a urinary ultrasound examination is needed to rule out the presence of urinary stones.
