Although acute muscular rheumatism is generally conceded to be an infectious process, the myalgias and milder forms of myositis are not so definitely accepted as such. Myalgic pains are considered by Taylor1 to be the result of faulty metabolism, by Gordon2 of excessive katabolism from over-exertion of muscle cells, and by Profanter3 as the peripheral expression of pain caused by defective function or injury of visceral organs.
