Everyone's fibro management is different. Below are some of the things which have worked for me
Exercise: walking with trekking poles, yoga, body weight exercises and stretches. if you have a area with reoccurring pain, then work on strengthening and stretching that area. Fibro attacks you where you are the weakest.

Nutrition: lowering or removing the following items from my diet: processed meats, gluten, food dyes, artificial sweeteners, high fructose corn syrup. I am also focusing in improving by gut health by increasing my fiber intake.

Supplements: Vitamin D + K2 (3000mg per day) is an important supplement. I am most comfortable if my Vitamin D score is 60 or higher. Iron bisglycinate (25 mg) helps keep my energy level up. Again a test score of 60 or more is ideal. Magnesium glycinate helps town down the cramping and pain. Palmitoylethanolamide (PEA) (600 to 900 mg) helps reduce pain and inflammation. I can really tell when I do not take this one. The quality of the supplement mentioned before is important. Not all brands are created equal. I also do not recommend the use of tablets.

Pharmaceuticals: Naltroxne 1.5 mg twice / day and 10 mg of escitalopram twice a day, and 5% lidoderm patches and cream (put the medicine where the pain is).

other intervention: Infra-red heating pad, weighted blanket, cognitive behavioral therapy, yoga, walking with trekking sticks, rest

I hope this helps.
