Today around noon, I developed a sharp pain in my lower left abdominal area. It has been pretty constant and hurts worse when I bend, squat, or move around. At first I thought it was gas, but it does not seem to be going away. I tried to use the restroom and pushed to see if I needed to have a bowel movement, but that is pretty painful. Is it common for built up gas to cause so much pain for an extended time? Should I be worried?
