So, my friend had to go to the Dr. to have something checked out. They told him we can either give you a Penicillin shot or you can take some pills for a week(not allergic to anything). Easy decision "can I pin myself?". The nurse says bend over and slams the needle in the cheek, then.....FIRE. As related from my friend-Fire starting at the injection point and what felt like acid radiating out through every vein in his body. Just like a zombie movie where you see the vein turn black as the virus destroys every blood cell and you can see it travel from the bite, through the veins, to the heart and then exploding every where.. Absolutely amazing. Then as soon as the fire died, freezing cold, teeth shattering body shaking cold. F this I'm out of here, F-ing Kaiser. It's over 100 degrees outside so you can imagine how hot the car is. Doesn't matter, get in crank up the heater, still freeing cold. Get home, jump in bed, buried in blankets and fall asleep. Wake up a few hours later, good as new.
