Hi and thanks for this query.
Acute neck and shoulder pain
without any other associated symptoms is often caused by poor positioning of the head and neck most especially during sleep. It can also be the case when we have to sit upright and don't adopt a good posture. We should always strive to sit upright for best vertebral
I will suggest that you monitor this pain over a few days. For now, you may consider having some pain medications. If the symptoms should get worse of stay the same or new ones develop, then you should go to the hospital to make sure there is nothing abnormal going on. I don't think at this time that the injury
is at the origin of this pain though should not be totally disregarded.
I hope you find this useful and informative. If you have more questions, please ask us and we shall gladly provide answers. I wish you good health.
