I have a "line" that starts just above my belly button and then goes up about 3 or 4 inches and then curves a little to the right and then I can't feel it anymore. If I lay on my back and press on my abdomen I can feel it. This may sound weird but when I lay on my back and raise my legs in the air there is like a raised line about 3 or 4 inches long on my abdomen, and an inch or so high, very obvious. Its soft and the only tender spot is right above the naval. But there is definitely something there. Any ideas what it might be? I am overweight and am having some stomachaches and loose, small bowel movements.

My advice is to go see your doctor. Might be nothing but can't hurt to see what he/she thinks.
