I have had 4.

They feel like what I imagine a GSW to the abdomen feels like.

I can tell you that I noticed a pattern- I would get them from cutting weight.

One of the ways I would cut was to ramp up my water intake to nearly 1 gallon a day of distilled water.
The higher intake of water leaves your body well hydrated.
But the distilled water has no natural minerals or salts in it, and your body cannot hold onto it, so you just sweat and pee it out.
Then a day or so before you begin your cut, stop drinking water.
Your body is used to being well lubed by the gallon a day, now before it gets back in sync, it dumps a gallon or so, this is good for almost 10 pounds of weight, and a very striated, vascular "look."

Afterwards, if I did not replenish my water and salt intake, boom, kidney stone.

It hurt so bad, that I literally went into shock. They had to give me a shot of adrenaline to get a pulse, as all my blood was pooling in my chest and abdomen. Doctor said I would have died in another 15 minutes from shock.
