It was nearly 10 years ago, with diabetes you can get neuropathy, which I have, and basically you can't feel much, by the time you realise something might be wrong it's often too late, that was the case with me, had no pain, even when they cut it off, indeed the worst bit was the super strong IV antibiotics, 2 different ones at the same time for a week, didn't half mess up my guts for weeks!
I lost my pinky toe, but toes are way more important than you'd think, even just the loss of a tiny toe has screwed up my balance big time, been wobbly ever since.
I was lucky, another day or two and I'd have probably lost most of my foot, earlier this year I had a scare, I managed to get a small cut on the same foot, I was treating it but iy went bad pretty much overnight, that earned me 3 nights in the hospital and the bloody antibiotics again
I can joke about it now (when my mrs isn't around) but it's a serious issue and most people who are vulnerable to it don't really understand the risks
