Is something wrong with my Intraoral incision after sliding genioplasty? (Photo)

I had s.g 7 weeks ago. The chin bone was forwarded 4-5 mm and vertically heightened as well. I am really worried because ever since i regained full feeling, I have felt the edge of augmented chin bone rubbing against incision in lower lip, as if placed too high, and I worry scar is not healing properly because of it. I have begun to notice stiff "threads" around incision, and lower lip is all stiff and tight. My surgeon sais I should just wait and see??? Really?
