Had a breast reduction a few days ago, one nipple is inverted and the other is really fat. Will they go back to natural shape?

I just got a reduction done a few days ago and one of my nipples have been sewed back on in a triangle and become inverted. Whilst the other one is really fat like the Areola puffs out with the nipple. Is this normal ? And are my nipples going to go back to looking normal like the naturally were ?
