Agreed. Stress often causes neuropathy symptoms to worsen. It certainly affects me.

Did you have a general anaesthetic for your foot procedure? If so do you know if nitrous oxide (N2O) was used? N2O oxidises vitamin B12, so if you are B12 deficient an anaesthetic could make things a whole lot worse. Most anaesthetists think it is a minor issue and don't hesitate to use N2O in any patient. A senior anaesthetist I know who has looked into this issue told me that 2 - 4 hours of N2O anaesthetic can destroy all the stored B12 in a normal adult.
