What does high c reactive protein mean with thyroid nodules? and vitamin d defiency?

Nothing: Elevated CRP means nothing in this context. You do need to get a little bit of sunlight and/or some supplemental vitamin D and keep an eye on the nodules. Report any that start growing fast.

CRP: The C-reactive protein is a completely non-specific measure of inflammation and cannot be interpreted without a full understanding of the clinical presentation. It is very unlikely to be due to vitamin D deficiency and whether it is related to the thyroid nodules depends upon what these nodules are composed of.
