The new system, comprising sensory nerves found on blood vessels and sweat glands, is not nearly as potent, but does allow people to sense temperatures and textures. The research suggests that the system may play a role in chronic pain disorders such as migraines and fibromyalgia, conditions whose causes remain a mystery."
