Tks for responding. Just to clarify, I am facing a disciplinary hearing regarding going to the gym for a light work out after I recovered from the headache. (No weightlifting), and need an expert medical opinion regarding this issue. I have always relied on exercises to aid in my recovery from any illness, and have always found that it works for me. So you are prepared to state that in you medical opinion light exercises is advisable depending on the state of recovery and the individual?
