Does Morgellons cause muscle twitching?
Morgellons is just a long list of symptoms, not a disease, so it can’t “cause” anything. But the list of supposed symptoms was extended to include “uncontrollable muscle twitching” after a report (May 2006) that former Oakland A’s pitcher Billy Koch has Morgellons. The extensive Morgellons Research Foundation’s “Case Definition”, written (Feb 14 2006) a few months before the Koch report, does not mention muscle twitching even as a secondary symptom. Koch no longer claims to have ever had Morgellons.
