Removing Silicone Injections on Butt?

I also have had silicon injected in my buttock and I want to have it removed, I believe I have developed some granulomas and I am very uncomfortable at night and sleeping. I am scared and want it removed if possible.

I was very young and stupid and I am still young and want to make sure I have a long and healthy life - so anything you can tell me to help would be helpful.
