who has been suffering from Post Traumatic
Concussion for more than 3 months. He has returned to teaching
in November, but still suffers daily from headaches, sometimes dizziness, and certainly drained & tired by the end of the day. We have paid for absolute full medical testing to be sure there are no other underlying causes, and so far, nothing has come up. He also had a CTScan which also came up OK. However, about 8 days ago he developed an unvoluntary head "jerking".
