Weird. Maybe they poked a giant nerve line.
There was a blood battle going on at my campus a couple weeks ago and I remember someone saying "They poked me over and over but they never found the vein"

So I had a leak in my radiator. I put some additive in it to fix it. It mostly fixed the leakage, but it screwed up the thermostat.
Whenever I drive my truck the temperature goes up steadily. It gets to red, and stays there for about 30 seconds then it drops to cold. Then it goes up again...
