Thank you everyone for your answers. I did sustain a whiplash, but unfortunately, I have not been able to get neck treatments as neck manipulation worsens my concussion symptoms(in particular, dizziness, nausea, headache). It could be that I was was unlucky and both a chiro and RMT that I saw were not mindful of my brain injury. I am getting acupuncture for it, but do you think I should do more? Any recommendations?

I got a neck MRI done, and I was told that "everything is normal". Do these things show up on MRI?
