White Bump Along Rhinoplasty Incision

I had a nose job (Rhinoplasty) 2 years ago. After a year, I noticed a small bump inside my nose where the incision was made to insert the silicone (I'm not really sure if it's called silicone or something else). All throughout that years, the small bump either bleeds or is always wet and I had to carry a tissue with me to wipe it everywhere I go.

Now, the bump started to disappear. But I noticed a white thing stuck on that same place where I had the bump. I tried to peek inside my nose and I really saw a white hard thing coming out from where I had the incision. My guess is, it is the silicon itself that is starting to come out. Can anybody tell me what it is? Would it damage my nose? Is it really possible that the silicone itself would come out of the skin? It also bleeds sometimes. It doesn't hurt, but I'm really worried. How does a surgical clinic charge for a check-up? And how much does it usually cost?
