<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Ive been experiencing pain and discomfort while urinating. I also have the urge to urinate frequently.  <response>: Based on your symptoms, I would like to run some tests. Well start with a urinalysis to check for any infections. Then, well perform a pelvis exam to see if there are any physical causes. If necessary, we may also do a CT scan or an endoscopy and biopsy of your urinary tract. Additionally, we may need to do an ultrasound and blood culture. Finally, well do a rectal examination to check for any prostate issues.
