Whiplash This is a type of injury which is caused by sharp, quick and forceful back and forth movement of the neck; much similar to a whiplash. Generally, it is caused by car accidents where the neck suddenly accelerates forward and backward after a collision or impact. Athletes and sportsmen also suffer from this problem and sports which involve physical contact can cause whiplash too. http://www.metrophysio.co.uk/whiplash-causes-and-treatment
Rotator cuff tear is a common cause of pain and discomfort among adults. It weakens the shoulder and even the simplest of tasks, such as combing your hair, can become extremely difficult and painful to perform. It is caused when one or more of the tendons of the four rotator cuff muscle are torn or injured. Being a common shoulder injury, rotator cuff tear can disable simple movements and can become quite problematic if it is not treated properly.
