How To Treat Gap In My Cheekbone?

Hi, may I answer your health queries right now ? Please type your query here...I had an accident about 5 years ago, feel down a flight of stairs hit a cigarette machine at the bottom, knocked my self out and cut around my eye, from my eyebrow to my cheekbone. I was in significant pain obviously afterwards and couldn't eat solid food. I went back to the hospital and had further X-rays to my cheekbone as it was numb and hurt a lot! It was discovered I had a hairline fracture. Now 5 years on, the gap in my cheekbone is getting bigger I can put my fingertip in it, it's number, and my eye feels like it's sagging. And it is slightly. I had no aftercare from hospital after accident apart from removing the stitches.

What should I do, I mentionedit to my gp last year but he dismissed there was anything wrong and only if my face basically collapsed that something would be done
