Lightheadedness is not really a concussion symptom past the first few hours. It is common to anxiety, especially when it shows up later. Some confuse dizziness with lightheadedness.

The whiplash would easily cause some or all of these symptoms. Disturbing your inner ear could also cause them. You could have dislodged the crystals in the inner ear that help you know various head positions. If laying down helps, that could be an indicator.

Ask your doctor for a referral to a vestibular therapist. Maybe you can be put through the Epley Maneuver to try to reset the crystals in your ear.

This type of vestibular trauma can make life miserable. Just moving can make you feel lousy.

Thank you, Mark.

The therapist that I’m seeing did the maneuver with me in the past and it wasn’t the case. Could it be a new problem due to a whiplash?

I just don’t remember feeling so lousy and 🤢 nauseated.. laying down helps a little bit nausea is still there

It might be worth trying again. The whiplash of the bump could have upset things just recently.

There are some tests that can challenge your vestibular system. One follows your eyes as you tip and turn. Ask your physical therapist or vestibular therapist for an assessment.

Do you do any better when resting in the dark? Vision is a big part of balance. An eye issue can trigger dizziness and nausea.
