I always have a urgent need to urinate, and I have to go urinate every 2 to 3 hours. I have no pain or burning with urinating but the flow is always weak, sometimes have drips after that.

You are more likely to have prostatitis or cystitis. I suggest you have a test in hospital to confirm it. 
The herbal medicine can cure prostatitis and cystitis effectively and completely. It does not have any side effects and will not cause drug resistance like antibiotic. It can not only cure prostatitis, but also improve immunity. After the disease cure complete, all symptoms will disappear.
