The cramps are very much part of the PN,and alot of people get them. I had really bad cramps for quite a while. I also had spasms & dystonia in my foot. It eventually abated,and I have found the cramping to be transient. People have advised me to take Magnesium,and so I use Magnesium Forte and it has helped alot.

As far as the sprained ankle feeling, is it like a deep bone type pain or is it more muscular?
