Lost all feeling in my breasts 2 years after breast augmentation. Will it ever come back? Is there a deeper problem?

I had a tubular breast correction with augmentation 2 years ago. I was 19 and I worked constantly to earn enough to correct them. They were affecting me my whole life, especially mentally. I had back problems from constantly slouching (to hide by breasts). The doctor "lowered" my fold by 2 inches, putting 3/4 of the impl. under the muscle. I lost ALL breast feeling since, and now it's been 2 years. Will it ever come back? Is there a deeper problem? My doc is retired, where should I seek help?
