I guess time for an update to this. Mine healed on the 12th day of the surgery and it happened pretty much instantly. Pain reduced to 5/10 on the 11th day and pretty much disappeared the next day.
Still, it was the worst week of my life pain-wise. I lost a few kilos.
Apparently it happens with some of the patients and the intensity varies from one person to another.
Doctors and nurses just play it down, don't tell you or don't care afterwards.
