Pain behind belly button when stretching

Digestive health

Earlier today I suddenly had a sharp pain behing my belly button, slightly to the right. It only hurts when I stretch, touch wood no other syptoms yet. Panicking it could be appendicitis, or would this be a constant pain?

I have had it a couple of other times in the last few months but very subtle pains that have passed quickly. Today it hurt for about an hour and a half I then layed down and stood up quickly and felt like somoene had pulled something in my belly button.

Do you think you have pulled a muscle? See your doctor if the pain lasts longer than a week.
