I have had numerous broken bones, bad knees and worn out shoulders for most of my adult life. Bacterial menigitius almost got me as a youngster, and melanoma that spread to lymph nodes. By far ,and I mean WAY far ,the worst thing I ever been through was having a stent removed from a kidney through the natural course of drainage after a kidney stone removal with no pain deadner other than the doc saying , "this is gonna suck , but I will make it quick!!!!!"
