Hi John: I do have a herniated L4-L5 with chronic sciatica (interestingly, and thankfully the sciatica has sort of been hibernating for the last several months, probably because I've rarely been out of bed in that time) but when it's "turned on" the pain is just as you describe and is nearly unbearable. I wanted to clarify that the main reason my onc wouldn't give me Folfox is because I have minimal diabetic neuropathy in my feet, which feels a lot like how people on the board describe their Oxi neuropathy. She was very sure that the Oxi would make the neuropathy I already have much worse, and definitely permanent.
I hope you feel better soon,
