Thanks for tha valuable input.
Well, this seems more like an infection, most likely Urethritis, or Cystitis, or a combination of both.
This can cause similar sensations, specially at the end of urination, making you feel un-satisfied and a continuous desire to pee.
Many a times the infections are subclinical, and some times mild. These mild infection may undergo spontaneous resolution even with out any treatment.
You should get a Urine Examination done to look for this possibility.
If deemed necessary, an Ultrasound will be helpful in providing information about other pelvic structures like uterus, so discuss this with your treating doctor.
Keep yourslef well hydrated, and use Cranberry, and this helps.
Kindest Regards XXXXX XXXXX luck.
