If its a 7 day course, it might take the full 7 days to fully improve. 3 days isn't all that long.

I got the urine culture last Wednesday and Monday they reported no growth. So, I guess I will call and request the blood test. I was just figuring with 4 days left on the doxycycline, the burning should be gone by now?
I would by blood test, and make sure he tests your urine for bacteria. Have him send it out and get cultured.

Well, I have the pain every time I go to the bathroom, so I guess I need to call my doctor today. I am to ask to be tested for herpes, correct? specifically by blood test?
Ask your doctor about the above possibility. If it is herpes, there is medication that can speed recovery and suppress recurrences.
You should get tested for Herpes via type specific blood test and a swab the next time you have the pain. It could be a herpetic infection. That would not respond to antibiotics and may recur.
