If whiplash causes pain in your neck from it being jerked forcefully, why does it affect the nerves in your arm?
Whiplash, which occurs if your head is jerked violently from front to back, can and does cause pain in the neck area. However, it's not just the muscles and soft tissues that are hurt, the nerves can be affected too from the violent shake. If there is pressure on the nerves, this can cause numbness or other nerve-related symptoms.
