No I am not taking any medication. Normally no problem passing urine flow is ok, Monday night after first prep I ran a fever at 6;30pm approx 99.2 then at 8;30pm approx 100.5 at 10;30 it was 102.5 I went to bed and the next morning it was 99.1 at the doctors office.

Wednesday the day after the colonoscopy I was having problems going and it was very dark. I went to the Doctor did some lab work for kidney infection or urinary tract infection all tests came back clear. I have been thinking about this all night I think I must be dehydrated. Imgoing to try massive amounts of water today and see if that will help. I have an appointment with the doc 9am Friday. And appointments at MD Anderson in Houston May 10-13th here I will see an urologist


Usually pain while ejaculation indicates prostate infection. Sometimes it can happen if you ejaculate after a long time .
Urine tests can come negative in prostate infection as the prostate gland is deeply seated . But it is a good fact that the urine test is negative ruling out urinary infection.

I would advise you get a rectal examination to get a feel of the prostate. An urine examination after prostate massage can make urine exam more accurate and positive.

If the urine exam comes positive then antibiotics for 4 weeks is recommended. If not then it may not be significant and some painkillers will correct the problem.

Only if the problem persists then further tests like rectal ultrasound may be required.

I hope this helps you.
