For the last two weeks I have experienced incresing discomfort in my bottom and a wave of discomfort that flows under my bottom up to my scrotum and up my penis. It is not painful as such and fels like I am about to pooh when in fact I dont need to go. The problem occurs every hour or so and lasts about four or five waves before stopping, although in the background there is a feeling I need to pooh. I feel slightly blocked up, although i'm not constipated.
Do I need help? Is this serious?
