Don’t think as a rule you see your surgeon again till 6 weeks post op. I’ve just got back from my 2nd post op appointment today(I had to have another 2 weeks post op coz I had a nipple lift) and I’m 16 days post op. The nurse said I will see her again for my 6 week appointment and see the surgeon too on the same day hopefully.
As for seeing anther doctor, I doubt it if it’s for a post op check up, as it wont be that surgeons work he’s looking at and checking. I’m pretty sure you’d need to go see the same surgeon. Can always ring your PC to ask though xx
