There has been a bit of a set-back. The part of my wound that had been healing very slowly but reasonably surely decided to metamorphose into something that looks like a special effect from a Sci-Fi  horror film – a fetid, putrefying chasm out of which, any moment, some kind of hideous alien will emerge, hauling its dripping torso from the slough.  I returned to the mother ship to show it to my surgeon and wound viability nurse.  There was some talk of maggots – apparently they clean up this kind of wound particularly well.  (You can get free- range ones or ones that come in a little teabag-like container.)  But in the end, they opted for a big dose of antibiotics and a complex regime of daily dressings to be administered at the rehab centre.  I was rather disappointed.
