For the past few days I have had a tugging sensation just below my belly button; it came on quite suddenly. At first it was very painful, it felt almost like I was being stabbed and I couldn't move without pain. It felt like something in my stomach was being stretched out, that was not meant to be. Now, a couple of days later, it still feels very uncomfortable, especially if I touch the area. All the information I can find online points towards either pregnancy or obesity, of which I am definitely neither. I don't want to go to the doctors if it's nothing, but I am worried about it. Also there does seem to be a lump when I press down, but that could have been there before and I have only just noticed because of the pain. Hope someone can help, thanks.
