Patience is a real virtue for this one - it can most certainly linger. On the positive side, it can also keep getting better if ever so slowly. My oncologist suggested vitamin B, purely on the basis that some people found it helpful, no promises! My symptoms stopped getting worse when I took it, so I still do. More recently I have found paraffin wax pedicures fantastic - a bit indulgent, and it may just make me feel good generally (not a bad idea!!), but the soles of my feet and heels feel much improved for several days after.
