My daughter just passed the one-year anniversary of her injury. Exercise was a big trigger.

She stopped exercising altogether for a couple months, then started on an eliptical machine at 2 minutes. After five days or so at two minutes, without symptoms, she increased to 3 minutes, and so on. It seemed to take FOREVER but she is now able to ride bikes, run, play frisbee, swim, etc., with only an occassional and short-lived headache or nausea.

This return to exercise gave her a sense of control over her own healing that honestly did more to help her than the actual exercise.

Ditto NancyS...6 months seemed to be a huge turning point for my daughter cognitively and with physical symptoms (fatigue, nausea, headaches, lightheadedness). Once the daily symptoms started to subside somewhat it was easier to chase down potential causes for individual symptoms. In my daughter's case it was damage to optic nerve. It was all muddled together before 6 months so it was hard to differentiate.

All the best to you-
