Since joining this site, I have learnt a great deal about PMR and GCA.
I have read several post over the months and I have noticed a trend. Many of us with PMR have been found to be vitamin D deficient. I'm now beginning to wonder whether there is a link between the two. Is the vitamin deficiency causing PMR, or is the PMR causing the deficiency? Or is it just a coincidence? It would be very interesting to find out if there is a correlation between the two. What do others think?
