liquid Silicone in Face - Like Grains of Sand. Can it be fixed?

I had liquid silicone injected in my face over ten years ago. I have been getting cortisone injections for several years to get rid of the little lumps on my lower face. I stopped because I ran out of mpney and the little pebble like lumps came back. What can be done for this? I am now 60 years old, my skin is thinner, and I cannot find a doctor that knows what to do about this condition.
