George North has revealed some of his struggles with post-concussion symptoms as he tries to get back on the playing field.
The Northampton Saints and Wales winger is currently out of action after he was advised, by doctors, to take a month away from rugby.
North sustained two concussive blows in a Six Nations match against England, in February, a little over a month later and North was knocked unconscious after taking a knee to the head.
The Welshman told BT Sport's Rugby Tonight that he is hopeful of a full return to contact soon but admits 'some days are terrible' and he has been forced to sit out sessions.
