For the past few days i have been experiencing a burning in my belly button and it's starting to swell a bit. it hurts mostly when i bend down on get up when i touch it it's sore right on top of my belly button and i get a sharp pain?

Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. You may have infection in the depth of the belly button. Clean it out with a Q tip and apply antibiotic ointment like Neosporin. If that does not help in a week or so it would be prudent to see your doctor. Wish you good health!
