Last night I had to urinate badly and could not find a bathroom. When I did go it took about 3 minites to get the flow started when I felt full.?

Sounds like BPH. You describe common symptoms of BPH or bothersome urinary symptoms caused by enlarged prostate. Symptoms include weak stream, difficulty starting stream, hesitency, urinary frequency/urgency, nocturia. I would see your medical doctor. He will likely perform an examination of your prostate and may consider starting medication to treat your bothersome urinary symptoms.
