Do you know what year you had the hepatitis b vaccine? I'm thinking that same vaccine caused my peripheral neuropathy. I was in my early 30s, healthy, fit. Then wala I end up with this chronic condition. I believe I had 2 of the 3 series. I have small nerve damage which causes a fever of sorts in my forefeet. They get bright red and hot, the only treatment that works, cold water or ice packs. My podiatrist told me years ago not to put cold on like that but it's the only thing that works fast.
