Hello, I'm Donner60. I wanted to let you know that I undid one of your recent contributions —the one you made with this edit to Post-concussion syndrome— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 03:38, 14 February 2015 (UTC)
