Whats the most physically painful thing youve ever experienced?

For me it was when I had surgery on my foot/ankle. They had to scrape away the cartilage on two bones that touched each other so that they would then fuse together. But after the operation they put me in a cast that was too tight. When my foot started to swell all that pressure didn't have anywhere to go so it was pressing on those newly scraped bones. They finally gave up on the morphine injections and figured out that they needed to remove the cast and give me a new one.
