Hello djorn,

Welcome to the NeuroTalk Support Groups.

I can't really help you with your questions I'm sorry but I just wanted to mentioned that a long time ago when researching some info for someone I read that people with Fibromyalgia and other chronic pain conditions had increased amounts of something called Substance P.

Perhaps you have the opposite and have decreased amounts of Substance P for some reason.

I have absolutely no idea if this is something worth investigating but thought I'd post for you anyway.
