Causes of Trigger Points
Trigger points are small, pea-like, contracted knots in the muscles that cause pain in the muscle attachments. The term "trigger points" was created in the 1940s by Janet G.Travell, M.D., who developed new anesthetic techniques to treat muscle spasms. Later, Travell and her colleague David G. Simons, M.D. continued their research and published "Myofascial Pain and Dysfunction: The Trigger Point Manual."
