has fasting caused nerve damage?

Hello

5 days ago I completed a 6-day fast - under medical supervision - and have nearly completed the refeeding staqe. The fast itself went very well. I had lots of energy and didn't suffer any severe detox symptoms at all. A day or two after returning home, I noticed that my right foot was slapping down on the ground when walking. I paid it no heed. Today, however, I tried moving my foot around and noticed I cannot draw my foot upwards towards me - like you do when you stand on your heels by drawing your toes upwards. I was a bit alarmed at this as the muscle operating that movement doesn't seem to have been diminished, and I am a little bit worried some nerve damage has ocurred.

Should I be concerned or is this normal? Any advice would be very welcome.

Thanks

Koldo.
