What Causes Burning Sensation In Penis And Frequent Need To Urinate?

Yesterday I had a pain in my left kidney accompanied by a sore left testicle. Both were a very dull painful ache. Both those symptoms then eased and since then I've had the most unbearable burning sensation coursing through my penis. I constantly feel desperate to pee and when I do, it's very little. I feel DESPERATE to pee, even straight after I've been.
