Re: Neck injury and numb pinky fingers (both sides)?
Hi -- most of the cervical (neck) folks hang out in the Spinal Cord Disorders area. I have had some issues with my neck which included numbness and tingling in my left hand. In my case, it was caused by a bulging disc pressing into the left foramen. The foramen is the area where the nerves exit the spine to go out to the different areas of the body.
You may have some swelling from the whiplash and associated inflammation that is causing those nerves to be impinged. Or, you may have damage to the cervical discs. It's a good sign that the tingling goes away, but you probably want to have an MRI to rule out disc damage. Also, since you are you soon post-injury, don't forget to ice, as this will help reduce inflammation.
