I am a 24 year old, sexually active male. About a week ago I started experiencing some discomfort/pain while urinating and some minor irritation at other times at the tip of my penis and the beginning of my urethra. While urinating the discomfort/pain (which is a stinging pain mostly) usually occurs when I begin to urinate and when my urine stream is coming to an end. In addition to the pain, I feel like I have to go pee quite often, even when it turns out I did not have much urine to excrete. Also, on a couple occasions over the past week, I have noticed small amounts of blood in the toilet after I have finished urinating, and my urine has a slight cloudiness to it. If it is relevant at all (in case of possible kidney infection or something), I have had what I believe to be a minor sinus infection for quite some time that I have left untreated. I have been drinking plenty of water and added cranberry juice into my diet to see whether I could clear this up myself. No luck so far. I appreciate any responses. Thank you.
