For a few days now, I have noticed a slight pain on the area a few inches below my belly button (near my pubic hair). It's a small area on the left side that is near my leg. I have no idea what this slight pain could be. it seems to be worse when I sit down. The area is not swollen or hard and there are no physical lumps or anything. What could be be the cause? I'm a bit worried having it checked my a doctor. What would they do?
