Hi, I have a small lump to the very right of my belly button. I just noticed this yesterday, its very small and i can feel it about the size of a dime. It has a burning sensation but does not hurt when i cough, bend over, etc. It almost feels like an ingrown hair- very similar feeling. But how would I have a hair on my belly button? I am afraid this could be a hernia, but it just came about last night so quickly
