Chin lipo post-op dimple pit: Will it go away? (photo)

I'm just over 3 months post-op on a chin implant and lipo and I have this dimple in the middle of my neck, see blue arrow. Also one side of my lower neck is still bigger than the other, it's the area with the shadow, marked with green arrow. My surgeon says dimple likely caused by a burst blood vessel and will fill back in and other part is swelling. But I'm worried given how much time has passed and they're still there and I'm wondering if anybody else can weigh in? Did he mess up? Thank you!
