Why does my lower abdomen and anus hurt when I sit, walk, cough, or sneeze? I m not constipated I eat a very good diet. I m not overweight and I don t have any medical issues besides asthma. even though I do go to the bathroom on the regular it hurts to push at all, its not like I have to push but you know just the regular going to take a bowl movement hurts. Also, I don t have hemroids.
