The exact cause of fibromyalgia is still unknown, but it is believed to be a complex interplay of genetic, environmental, and psychological factors.
Research suggests that people with fibromyalgia have an amplified pain response to stimuli that would not normally be painful, such as touch or pressure. This may be due to changes in the way the brain processes pain signals, which could be caused by abnormalities in the neurotransmitters that regulate pain perception.
Other factors that have been associated with an increased risk of fibromyalgia include physical or emotional trauma, infections, autoimmune diseases, and sleep disorders. Additionally, some studies suggest that genetics may play a role in the development of fibromyalgia, as it appears to run in families.
Overall, it is likely that fibromyalgia arises from a combination of different factors, and research is ongoing to better understand its underlying causes.
