Sorry if I have put this in the wrong place, I wasn't sure where to post it.

I know no one can obviously give me a definite answer on this, I just wondered about other people's experiences.

So a couple of years ago I sustained concussion in a car accident, I was knocked out for a minute or so but my CT scans were clear. My short term memory was gone and I just laid there constantly talking rubbish and repeating myself every 5 minutes. I am having a nerve block for CRPS in a couple of weeks and I am being sedated for it, is it likely that the sedation will have the same effect on me as the concussion? I just remember how traumatic and scary the whole thing was and Im really worried about being put through that again Has anyone else had the same experience with concussion and then again with sedation or general anaesthetic?
