Stomach skin numbness??

(this is all surface, not internal)

The small area of skin below my belly button feels numb, but not tingly. I more or less have extremely less feeling in that section. The area as a whole is only 2inches by 2inches....all other parts of my stomach feel normal to touch......

Example: lightly tracing my fingers across my stomach feels normal and tickly until I hit that spot, then I feel barely anything.

Does any one else have this? I assume it's a side effect of the skin stretching but I'm curious to know I'm not the only one.
