Sqad not necessary smoking. My next door neighbour has type 2 and has been in hospital 3 times this year for operations on her foot. The plastic surgeon is coming to see her today to see if he can save her foot, but if not, she will probably have an amputation and she has never smoked in her life. This all started because of an infection in her heel.
I hope she makes a swift and pain free recovery, Tony. I know a chap that had three toes removed when he stood on a land mine (he was a soldier at the time). It took him a little while to walk but now nobody would know. I hope your wife has a similar experience
