When I get fever, body pains, etc…, does the fever cause the body pains or does the flu virus cause the body pains?

When I get fever, body pains, etc…, does the fever cause the body pains or does the  flu virus cause the body pains?

The same is at least partially true for the muscle pain, although there may be some breakdown of muscle cells by the virus (myositis). ...Read more
