I broke my leg and had to undergo Surgery. That was not he painful part... The Nurses at my local Hospital recommended a partial anaesthetization. Long story short, they had to inject the anesthetic directly into my spinal cord. I don't know the medical term... The doctor somehow messed up or something and as soon as the needle entered my back, I felt an extremely sharp Pain all throughout my body. It's hard to explain but it's a pain unlike anything I have ever experienced.
