Floppy foot, numbness.... yeah, I have total numbness from knees down... I use a cane..... Burning persists above the knees but for the fact of the Boston Sci SCS with which I help manage such pain also with my cushion. Floppy foot? A physical therapist can prescribe for you an appliance which is a brace to hold the foot fixed so as to avoid the tripping phenomenon. I trip... I fall down stairs.... I did not go for the appliance. I have a cane and a wheelchair for LONG stints in malls, airports, museums and the like. I am much better about holding onto stair rails now.
I SO hope and pray you are able to fix the ultimate issues with the aid of your docs.... they just need to help you manage this PAIN!!!! No question about it!!!
Prayin,
