Hi, CatKittyFish, and welcome! I'm deficient in Vitamin D3 because I wear sunscreen whenever I'm out in the sun. Many of us are deficient in this vitamin and that can cause pain. I also use malic acid/magnesium supplements that help with pain.
You do need to keep moving with fibro so I do stretching exercises and walk at least a mile a day and this helps with pain and fatigue plus I pace myself when doing things. All of this helps.
Be sure to read Fibro 101...the first thread on the forum. There are links to good info about fibro and you will learn a lot there. There are links about Vitamin D3 and malic acid/magnesium supplements, too.
I'm looking forward to getting to know you better. Don't hesitate to ask questions because we are here to help you. Hope to hear more from you soon.
