I am having cramps in my lower stomach, right side of my lower naval. When I clear my throat or cough, I can feel pain in my lower area. I have had diarrhea (which is very unusual) for the last 2 days, but no fever. I do not have pain when I urinate. This pain has come and gone for the last several months, but nothing to excruciating, some days are more noticed than others. Most of the time, passing gas lessens any pain. I am a runner and a hiker and the pain has not kept me from exercising. I feel pain for when I sit up more than I do when laying down or standing up.
