If you look on the left side of the message board there is an icon called "cluster survey". Click on this. One of the questions is if anyone had sustained any injury or trauma before there CH began. Click on the "View survey results" button to view results and see how many people said yes. This will give you the best answer to your question. Hope this helps.
