My son has this, but not through chemotherapy
I bought him some sketcher type slipons yesterday,as his slippers were very soft and backless,he can walk a bit better in these as he can at least feel them around his feet
He has done a lof of heavy lifting in his work in the past and was told it was due to this,but had no help from his Dr,was supposed to have had cortisone injections about 3 years ago, never happened
I believe it is Vit B12 which helps with numbness and tingling in feet
He does have other health problems too
