By Perhaps a bit harsh; but, in this case, true.
About a month or so ago he started to develop some blistering on his foot; more specifically on his big toe. At the time we told him to go and see a Doctor. He ignored us, and it's gradually got worse. Finally, today, he went to see a Doctor.
Too late.
They've told him that it's gangrene. They've taken him into hospital and whilst at first they had said that they were going to put him on antibiotics and see if that helped; it now transpires that they're likely to need to remove his big toe at the very least.
Oops
