I am a 44 yr old male in good health and not overweight. Approx. 5 days ago I began having an irritated bladder by which I mean it feels very uncomfortable and feels full most of the time even after urination. If I attempted to urinate every time I felt I need to it would be every 10-15 minutes but I know by the amount I drink when there is really something there or not. I do not have to get up in the night to go, I don't have a fever, do not have backpain, any discharge, nor do I have pain or burning feeling when urinating. Sometimes the discomfort feels like it is in the prostate area or deep in the colon. My GP did a prostate exam and said it seemed slightly tender but not inflamed. The urine sample was normal except high on the alkaline side. He did not prescribe antibiotics but recommended I drink lots of water and cranberry juice and see how it is in week. I am concerned I have a growth or something in my bladder that is causing this sensation. It seems to me that I do not have any of the usual symptoms of bladder infection or prostatistis yet have this intense irritation which, at times, is almost intolerable. Does this sound serious to you or do you have ideas as to what it could be? Thanks!
