Welcome to NeuroTalk! I'm sorry to hear about your accident. You came to the right place. There are plenty of good hearted people here to help you with your troubles.

The symptoms your describing sound very much like post-concussion syndrome. If you haven't had any of those tests done, I would get them done just to be on the safe side. You said the accident was pretty severe, so it would be well worth getting the MRI done to check for any bleeding or bruising on your brain. The EEG test would be to check for seizures and abnormal brain waves. I would get that done too just in case.

PCS symptoms tend to come and go. So just because you have a day or two without symptoms, doesn't mean your out of the woods. They can come right back and nip you in the butt.

If you have insurance, it should be no question to whether you get the tests done or not. It shouldn't cost you more than a co-pay.

I wish you the best of luck. Keep posting here, let us know how your doing.
