Urgency with urine that comes only little by little can still point to a mild urinary tract irritation, even without pain or blood. This matters more given your history of cystitis three months ago.
Next Steps
A urine routine and culture test will show if there's an infection or something else causing this.
Health Tips
Please don't restart the earlier syrup on your own this time. Since symptoms have come back, your doctor should examine you and test before prescribing anything new.
