Would it accomplish anything for me to get a cat scan or diffusion MRI(don't know what that is)? My car accident was 5.5 years ago. Cat scan right after didn't show any abnormality.

My vision was affected(convergence insifficiency)
Daily headaches
Fog
Light/sound sensitivity are main issues

Currently working with acupuncturist/massage guy that does pressure point release and gua sha(similar to cupping) to promote blood flow and get the neck/back muscles to relax.

For my own sake, I would like to see a scan and say, this is what's wrong with me. Even if there wasn't anything I can do about it at least my family might understand it's not in my head.
