I usually just say, that while my pain doesn't SHOW....it feels as if I've been scalded with boiling water - INSIDE AND OUT! That usually gets the point across.

It IS like noise! I try to think of it as my nerves screaming....either they are dying and scream in the process, or are hurt and crying OW! BIGTIME!, or protesting as they regrow and ask the brain very LOUDLY: OK WHAT DO I DO NOW????

It's like a high-tension-power-lines humm when you are near them. It's with you all of your waking and conscious life. I'm sort of used to it except on my worser days, but I have to tell you - IF it suddenly went away I sure would wonder if I was still alive!

I hope this all helps - j
