Incision pain

[Grateful mama 10]

Hey all:) I'm four weeks post op and had my first fill last Friday. For the most part my incisions have been slowly getting better. Just my large incision still kind if burny when bending or getting out of bed. Since my fill on Friday, my incision has seemed even more sore and hurts pretty bad when moving in bed or getting up. I even feel a little pulling on my port. Is this seem strange or is it just still part if the healing process and maybe aggravated by the fill? Thanks:)
