4 yrs post I have neuralgia on my left side w/ lump there and running a fever. Left areola is turning white. What could this be?

I had a breast reduction 4+ years ago. I do still have neuralgia on my left side. I also have had full body lymph node swelling (rapidly increasing), but the nodes under the left armpit and another "lump" in my left breast has caused pain for the last few days. I'm now running a fever. Doctors say tests show nothing. Now my left aureola is suddenly turning white. I live in a small town, and other people are also being blown off if the docs don't have answers. I just don't know what to do anymore.
