Worst medical thing you have experienced

I know what its like to be shot ,I was actually wondering the feeling you would feel and didnt have to wait long for it which was strange but I given up on wondering about bullshit. A carborundum wheel exploded while I was cutting through a block of stone my fault Id cut it with a thinner blade first and went for it with a new one that was thicker and it dragged it into it and exploded and piece slammed into my forearm and went into pieces which my GP had to pick out after I got numbed I got to see right in there going eww whats that white shit whats that smooth sack looking thing,is that the bone there? Nervous blabbing. Note: (never squirt a garden hose into a hole you have made in yourself it kills worse than the hole).
