Hi, I m very scared and concerned about a small firm lump the size of a grape that has appeared DIRECTLY below my belly button. It is no more than half an inch away from the navel, and it feels stiff yet tender when i touch it, and i can move it around as well. I was just feeling my stomach about three days ago, and i felt it. it was so ironic because i had unprotected sex about 7 days ago and took Plan v not even the next day. Point is, im very nervous and anxious to know what it is... I know it s not a hernia, since it isn t placed anywhere near where they say, and it s so small. Please, can you tell me what it is?
