postconcussion - I'm sorry to hear you've had a similar experience as the one I'm having, I'm glad I'm not alone. And neither are you! Thanks for your suggested methods of getting past it. I, too, am terrified this terrible symptom won't go away. It's the scariest feeling ever when your mind is lost and you just can't get a grip on it.

Mark - Your right, I did learn from this experience and I didn't bring any ear plugs. I'm slowly learning piece by piece what triggers my symptoms. I've got a list going now. What is the purpose of the ear plugs, might I ask? Is there a reason besides the headaches and physical symptoms the noise causes? I don't have very strong physical symptoms, really. Very very rare light headaches and occasional dizziness. The only problems I'm having are mental issues like brain fog and this "derealization" or whatever it is I'm experiencing. Do you think the noise and lights etc. effect the mental symptoms as well? If so, I'm going to take your advice on the ear plug thing and carry them with me everywhere I go.

And to update you on the blood pressure thing, I went to the ER the other day for similar symptoms to what I'm having now to have blood drawn, urine sample and chest x-ray to make sure there was no infection in my body causing it. While I was there, my blood pressure was back to normal. Which is the first time since the injury. Thanks God for that.
