Hi. I am a male, 62 years of age, exexcise regularly (75 minutes of treadmill and 90 minutes of weight lifting daily), heart rate 49bpm, and BY 112/55. Two days ago i was at a park where the restrooms were not open, and I needed to void. I always keep a plastic bottle in my car for such occasions. Normally I drink a very large volume of water but due to the cool weather my consumption drastically reduced. Yesterday I had an urgency to urinate (a non-normal experience for me). The experience was painful and the initial flow of urine was brown with tne later portion of the stream more bloody. This occur several times yesterday and today. Does this sound like an infection (bladder)?
