How soon should I have a hypertrophic scar injected? Mole removal by incision. (photos)

I had 9 moles removed exactly one month ago by incision. The scars looked great at first, small, thin- straight lines and very smooth/flat. About a week ago they stsrted to raise and get tender, now they are round, raised and red. I called the surgeon and the office told me it was too soon to inject them and to just wait and see?? To me I would think getting them early would be better? I'm upset that I swapped moles for these large red-raised scars... the one below is on my chest.
