Groups at higher risk for vitamin D deficiency
There's no evidence linking chronic widespread pain in the general population to vitamin D deficiency so it shouldn't be tested routinely.
Routine checking of baseline vitamin D level isn't indicated unless there's any of the following:
abnormalities of bone profile
additional physical signs.
In at-risk populations where vitamin D deficiency is suspected, it's reasonable to check vitamin D levels and/or considering an empirical trial of vitamin D therapy according to local guidelines.
However, whether correcting vitamin D will have an impact on widespread pain is less clear-cut. Download the National Osteoporosis Society's publication

Sufficiency is dependent on the mother’s vitamin D sufficiency level. Mother's milk typically contains about 25 IU/L of vitamin D.
As people age, the skin isn't able to synthesize vitamin D as effectively, and reduced kidney function impacts the ability to convert vitamin D.
Dark skinned people
Melanin in darker skin reduces the ability to produce vitamin D from sunlight exposure.
Limited sun exposure
Eliminates one of the two possible sources of vitamin D.
Vitamin D is fat soluble, which doesn't allow it to circulate as freely.
Antiepileptic medications can affect vitamin D metabolism leading to deficiency. Other
