Hi, sorry your message was missed.
There's a TBI forum here. Some member there may have some suggestions for you.

Unfortunately some of the forums are a little quiet of late.
What you're describing sounds very concerning and serious and I would only hope you could get another opinion ASAP to find out why this is happening. Perhaps related to fluid build up from your accident or something totally different.
I'm not sure if your neurologist actually did a EEG or did any recent scans like MRI or CT or even a PET scan.
