<bot>: Dear Friend. Welcome to Chat Doctor. I am Chat Doctor. I have read your query in detail. Furthermore, I understand your concern. We should first rule out the reason for developing Urinary Tract Infection (UTI). If you are still not relieved after Niacin injections, I would advise you:1. Urine culture and sensitivity2. Ultrasound abdomen with PUB.3. Kidney function test. This would help in knowing which organism is causing the infection and which antibiotic would work. Maintain good HY Chat Doctor. Complete the course of antibiotics prescribed by your doctor till the report of culture is available. This is my best advise for you based on available details. If you have any further query please ask me. Stay Healthy. ChatDoctor, MD
