“Rhinoplasty and Liposuction Scar and Tightness Issues.”

Hi, a little over four weeks ago I underwent a rhinoplasty and submental liposuction under my chin. I did this becuase I felt my nose was crooked and large, also I had the lipo becuase I was always bothered by the fat underneath my neck. It was always quick to get bigger if i gained even an extra pound! The nose also had a small bump I wanted to get rid of.

So here are some concerns I have. The scar underneath the neck is small but is tough and half of it is pinkish. I do have a keloid on my chest so this worries me, I am using a silicone product, any other suggestions?

Also more importantly my center neck muscle is still very tight, is this an issue? Also I can feel the cartilage he placed in my nose on the inside, it feels "crunchy" is this okay? Hows the scar look? Didnt they stitch it off center?
