I've just had a few days of suffering neck pain, due to pulling a muscle. I have ridden with it and I have to say it's been awful as I haven't been able to turn my head probably to view traffic behind me on a hack. It did also hurt with the impact. I would suggest if she has a long term injury that she consults her gp. Also perhaps see a chiropractor, physio or osteopath to see if manipulation and massage help. They can also recommend regular stretching exercises to help build up the neck, back and spinal muscles.
