Quick question-- my foot dystonia in the morning are my worst complaint--ive tried various things-- warmth-magnesium, etc without benefit--it definitely improves with anxiety reduction or distraction--so im wondering-if like with any involuntary muscle contraction-- that has to be ionized calcium -or intracellular calcium mediated in the end--whether or not the transition from sleep to wake which is associated with a mild decrease in carbon dioxide which will move calcium unto binding proteins and lower the ionized fraction---is at least partially responsible-- if it is-then maneuvers like breath holding or rebreathing-eg into a paper bag - would help or prevent them--anyone ever try???
