According to the American Medical Association (AMA), mycotoxins are linked to fibromyalgia . The longer the exposure, the worse the symptoms, so consult your doctor immediately if you’ve been exposed to fungal toxins.
6. Oxidative Stress
Oxidative stress occurs when free radicals are not neutralized adequately in the body. The resulting physiological stress is what causes oxidative stress, and it has been shown to be linked to the onset of fibromyalgia .
7. Intolerance to Food Ingredients
Yes, what you eat can make a difference. Try keeping a food journal and, alongside of it, track your pain symptoms. If you notice that your pain flare ups increase after consuming foods containing gluten or dairy, for example, share this information with your doctor. Together you can work on a dietary plan that may help mitigate some of your symptoms.
An underactive thyroid can sometimes cause symptoms that mirror those of fibromyalgia, including weakness, depression, and muscle pain. Your doctor can order blood tests to determine if that’s the cause of your symptoms.
Separate studies, noted by the NIH  and the University of Maryland  have found a link between the reduction of fibromyalgia-related pain and the addition of magnesium supplements to the diet. Talk to your doctor about finding the right supplement, as well as foods that can help you naturally increase your magnesium intake.
Small intestine bacterial overgrowth, or SIBO, is caused when an abnormally high number of bacteria exist in the upper part of the small intestine.
The bacteria, which are generally harmless, then become harmful, producing enzymes, toxins and harmful gases that cause intense pain and, sometimes, intestinal damage. If you experience these symptoms, talk to your doctor, as SIBO has been directly linked to fibromyalgia .
Finally, maintain a log of your symptoms. That way, when you do visit your doctor, you won’t be leaving anything out. Working together, you can treat your fibromyalgia symptoms, and get to the root cause.
