I have to strain all day and night sometimes usually every ten or twenty minutes at a time if need be. I have been straining for years everyday of my life since high school and I'm 51 now. I think my bladder is messed up or something. My urinary infection won't go away even though I'm on antibiotics and the straining makes it worse I think. If I happen not to strain for about 7 to 24 hours during the night the soreness disappears. I get too uncomfortable if I don't strain with feeling incomplete evacuation and have to get it out.it puts pressure on my bladder if I don't strain it out.
