Does dopamine really mitigate pain? If so, what part does dopamine shortfall play in chronic pain conditions such as fibromylagia, neuralgia and in the delayed and often exaggerated post exertional responses of ME/CFS? How does this factor overlap with other dopamine deficient conditions such as ADHD and parkinsons and how can the knowledge of it be used to hack a better life in chronic health cases where dopamine levels play such an intrinsic part?
