Their cause is somewhat controversial, not least because of the lack of an unambiguous definition of the condition. Subjectively, a muscle knot feels like it is somehow locked into a permanent state of contraction, but surgical biopsies of knotted muscle have found unusual protein deposits within the tissue, so it’s possible that the muscle is being prevented from contracting properly by these proteins.
