Whiplash Symptoms: Grade IV
The most severe whiplash injury is the one whose symptoms reach (or surpass) Grade IV. In most cases, these include all of the whiplash symptoms mentioned above, particularly the neurological ones, but they are more severe.
Grade IV also includes a fracture, misalignment, or displacement of at least one neck vertebra, which would put pressure on your spinal cord or nearby nerves, and could be the cause of more severe neurological symptoms.
In general, if your initial symptoms post-whiplash were severe and intense, you may be at high risk of developing Grade IV symptoms. Grade IV (or Long-term or chronic) symptoms of a whiplash injury can include the following:
- Persistent neck pain, muscle weakness and stiffness
- Chronic radiating headaches starting from the frontal skull
- Pain or numbness in the neck, upper back, shoulders, or upper arms
- Dizziness and balance problems (chronic, mostly due to damaged inner ears)
- Tinnitus (ringing in the ears) and vision issues due to disruption in reflexes
- Jaw pain, difficulty swallowing and hoarseness or loss of voice
- Loss of ability to feel the pain, heat, or cold sensations
- Nausea or vertigo (also known as cervical vertigo)
- Bone or nerve fracture/ dislocation/ misalignment
- Paraesthesia (“pins and needles” sensation)
