Raised puffy donut skin around incision? (Photo)

hello, i had gynecomastia surgery 6 months ago and while mostly it is healing well - i have one incision next to each nipple where the liposuction drain was - they use prolene sutures that had to come out a few days after surgery and at first the incision was flat and it still is, it’s actually almost white, but the skin around the incision scar is raised in a circle donut fashion? i can’t find anything online about why this may be, do i have any options to treat this raised hard skin?
