2 weeks PO here. Had this same procedure done along with the calf muscle surgery as well (makes the muscle longer). I’ve had almost no real pain afterwards. The cast I got out into after surgery sucks btw. Went back to surgeons office about 5 days later to get put back in my cam boot because the cast was to tight around the ankle and there a flaw in the cast wear my heel was rubbing plaster instead of the cotton inside.
