I don't know how big the wound is as it is on my back so I can't easily see it, but the nurse at my GP said it was deep. On the surface it was about an inch across.
When I was discharged from hospital I was told I would need to get it packed and dressed for about a week. The nurse on my first visit said it would be more likely 2. It's been 2 weeks now and saw a different nurse today who said she thinks it will be another 2 weeks. Dr Google suggests 10 -14 days are usual.
It's not a problem, it seems to be healing well, it's just I'm having to have it done on work time and while they have been patient so far there are a few raised eyebrows now as I originally said a week.
