Why do people with fibromyalgia have a heightened sense of smell and sensitivity to odors?
Fibromyalgia affects your central nervous system, which includes your brain, spinal cord, and the network of nerves throughout your body. This can lead to central sensitization, where your nervous system becomes overactive and reacts too strongly to various sensory signals.
Just like your body may amplify pain signals or interpret light touch as uncomfortable, it can also intensify smell signals. Your brain may process normal odors as much stronger than they actually are, or pick up on scents that others barely notice.
This heightened sensitivity isn't limited to smell. Many people with fibromyalgia experience similar amplification with other senses, including touch, sound, and even taste. It's all connected to how your nervous system processes sensory information.
The changes in brain chemicals (neurotransmitters) like dopamine and norepinephrine that occur with fibromyalgia play a role in controlling not just pain and mood, but also how you perceive sensory input, including smells.
While this sensitivity can be frustrating, understanding that it's a real neurological response rather than something you're imagining can be validating.
