@fmcfs & @abd Fibromyalgia symptoms CAN be drastically reduced by diet and lifestyle changes, but a person may not be cured. In fact, it is like "going into remission" with other diseases and disorders.
Going back to the old lifestyle, or changes like stress and the addition of other conditions or illnesses can cause the symptoms to come back.
I have had fibromyalgia for over 40 years. Removing gluten from my diet led to a huge reduction in my symptoms, to the point where I often felt "normal". BUT when I got a chronic lung infection, and needed serious long-term antibiotic therapy, every symptom roared back, worse than ever before. It took 2 years of pain management therapy to get back to where I was before the infection. Now, I am having a flare of RA symptoms, an increase in osteo-arthritic and seasonal allergies, and the symptoms are worse again. Even my rheumatologist uses my fibro symptoms as a gauge for how well my RA drugs are working.
So really, fibro is a condition that can "wax and wane" depending on other things going on, medication, stress, even weather.
PLEASE don't conclude that because symptoms are gone, there was a misdiagnosis.
@sueinmn you are parsing on semantics here. GF sensitivity is definitely helpful for FM patients, but so is not eating sugar and simple carbs because they also cause inflammation. So, it’s diagnosed over time. It took me a year to be diagnosed after 10 different specialists. A true FM syndrome would remain even if you are on a low carb, no sugar, no gluten diet. It would probably not be as painful, but it would be underlying. I mentioned misdiagnosis because doctors know very little about it, and are quick to give up and just say idiopathic pain, Fibromyalgia. A catch all.
