Could a vit d deficiency cause this I have had diagnosis of fibromyalgia for over 20 years and recently been diagnosed with vitamin D OA elevated C reac pro?

Yes, a vitamin D deficiency could contribute to fibromyalgia symptoms. Fibromyalgia is a chronic condition that causes widespread pain and tenderness in the muscles, tendons, and ligaments. While the exact cause of fibromyalgia is unknown, it is thought to be related to a combination of genetic and environmental factors. Vitamin D is essential for bone health and muscle function, and some research has suggested that low levels of vitamin D may be linked to an increased risk of developing fibromyalgia.

In addition, vitamin D deficiency has been associated with an increased risk of developing several other conditions that are commonly seen in people with fibromyalgia, such as chronic fatigue syndrome, depression, and anxiety.

- A study published in the journal "Pain Medicine" found that people with fibromyalgia had significantly lower levels of vitamin D than people without the condition.

- Another study, published in the journal "Rheumatology International," found that vitamin D supplementation improved pain and stiffness in people with fibromyalgia.

If you have been diagnosed with fibromyalgia, it is important to talk to your doctor about whether you may have a vitamin D deficiency. If you are deficient in vitamin D, your doctor may recommend taking a vitamin D supplement.
