chahci,

A CT or MRI at this point will be of little value. The CT will be undue radiation exposure. the MRI will just be an exhausting experience for one with auditory sensitivity. Unless he is exhibiting severe head aches or loss of balance or coordination, etc. imaging is not called for and will likely be normal.

I understand his struggle with the vacuum and clanking dishes. They can be auditorily over-stimulating. His awareness of needing to escape shows that he is understanding his symptoms well.

Interesting shiver comment. I have never experienced it 'that' way. I have experienced an overall shiver like a wave of nervous energy passing through my body.

It sounds like he just needs time with rest and quiet then a slow reintroduction to light and sound. Not much can be done from a treatment angle.

My best to you both.
