Q. Polymyalgia rheumatica has anyone had experience and delt with this specifically?

A. I have not heard of the Firefly being used for this condition. The best idea in this situation is to search Pubmed with the disease and photobiomodulation. This may render a study or article which you could then share. If you can’t find anything, you can always reference that photobiomodualtion is working at the cellular level to increase mitochondrial output of ATP.

After review of this disease I think the Firefly would be excellent to at least try.
