Thanks, John. I was aware that PMR might be triggered by a virus. I am interested in whether people with PMR have had a flare up or relapse during a virus. I’ve had a flare up with a cold.

No one knows what causes PMR. The citation above is representative of theorizing by some medical scientists, and it makes logical sense that there may be a virus, as yet unidentified, that causes or triggers PMR. If so, it would seem to be a persistent virus, like zoster or HIV, that hides in the body sometimes ("remission") and then pops out again. So what? Since no one has discovered such a virus, science cannot combat it. But I hate to feel helpless, as do so many posters here. There really is something we can do to fight PMR: work on boosting our own immune systems. It is the immune system that eliminates viruses (like colds or flu) from our bodies. Even if PMR does not result from a virus, a strong immune system is the best health tool we have. Nutritionists, physical therapists, doctors all have ways we can support our immune systems. Again, even should we fall short of achieving the powerful immunity we desire, just the fact that we are doing something, not just suffering from PMR, is itself a helpful psychological boost. [I have no credentials for this opinion.]

@christopherc topherc Interesting question I had covid in the last year or so now I have PMR Id be interested in finding out also . Haven't seen my rheumatologist yet but will ask him
