Possible hernia symptoms

Hey,

I have had a mild dull pain about 2 inches to the right an 2 inches down from my belly button in my abdomen. It used to just come and go and only bother me for about 2-3 days of each month. It's been persistent over the last week. It hurts when I do a situp and when I am either in the act of sitting down or standing up. I can't feel any bulge or tear really and the pain is very localized. i don't notice pain when I cough or sneeze really.

It seems pretty high for a hernia since it is right in the middle of my abdomen.

Does this sound like a hernia, or could it be a abdominal strain or something else?
