One of the most common types of brain damage found in people with fibromyalgia is a result of neurotransmitter dysregulation. It will not matter whether fibromyalgia or the neurotransmitter dysregulation comes first. However, the fact that there are neurotransmitter issues, can easily trigger the other. Neurotransmission is the process where the brain takes in signals and formulates responses as a result of the learned action and biochemical reaction.
With a condition like fibromyalgia where an entire disorder exists within the body, it makes real sense why the neurotransmitters can become dysregulated along with chronic pain and several other symptoms. If your brain is damaged, neurotransmitter dysregulation will be the first dysfunction. It can create a cluster of symptoms that can lead to fibromyalgia.
