Curious....

For like a month now I've felt like something was different and weird about my belly area. Especially when I touch it. It just don't feel right. I'm the type of person that notices every change in my body and this seems like a pretty weird and slightly big change. It feel weirdly shaped and feels like there is something wrong. It's sensitive to the touch too which is also weird. Had this every happen to someone else? If so was it anything bad?
