WHen I was younger i used to have bad cramp. i went to see a doctor and they performed x rays. the doctor the told me i was born with 2 sets of ribs and that if i continiued to have problems i would have to get one set taken out. years went by and i really didnt have any more problems and i still have the extra set of ribs and recent xrays. i just wanted to know if this have ever been heard of before?
