UPDATE: Green light from the medical experts!
After 6 months, I can officially report that I am completely healed.
During the past months, I did not sit still, but always trained with the brakes on. From now on, I can start training full time again under the guidance of Prof. Bourgois. The goal is to participate at the Brugge Boat Race on the 5th of March in my own club. From March, I will also resume training together with the national team (Belgian Sharks).
Thanks to the neurologist Dr Honoré for the good follow-up.
