In May 2013, Swedish researchers found a cause of pain for fibromyalgia and chronic muscle pains. It is a shortage of a pain relieving substance produced by the body’s cells, Palmitoylethanolamide (PEA).
A new treatment for fibromyalgia is now possible using the body’s own supplement palmitoylethanolamide. And now we understand why this is a good idea!
Fibromyalgia: an unpleasant condition that takes away a lot of joy from life! University researchers looked at the levels of PEA in painful muscles of patients and compared that with the PEA levels in the muscles of healthy people. 
They had the patients with chronic muscle pain, like fibromyalgia, do a few mild muscle exercises. Due to the activity of the muscles, the production of the pain relieving substance PEA increased, more for the chronic pain patients compared to healthy volunteers. However, after the exercise the level of the pain relieving substance dropped more in the muscles of the chronic pain patients than in the muscles of the healthy volunteers.
Fibromyalgia: low levels of PEA after muscle exertion
Palmitoylethanolamide (PEA) as a body’s own pain reliever was discovered in the previous century and PEA has been tested as a pain killer and anti-inflammatory substance on thousands of patients. PEA products can be used without any problems, as negative side effects have not been reported in more than 400 studies during the past 60+ years.
The authors closed the article with:
“The observation of the present study that chronic widespread pain does not trigger synthesis of the NAE’s (endogenous painkillers such as PEA) raises the possibility that chronic widespread pain patients could be helped by administration of exogenous PEA, which has been shown to have a good safety profile.”
Or in short: During chronic pain like in fibromyalgia there is a shortage of palmitoylethanolamide and taking a supplement of this substance is useful, especially because the substance is very safe.
