dablues,
I’m responding late to your post. It seems that this thread disappeared from my site. I don’t have neck problems.
I had not had a brain zap in a long time - maybe a year - then had one yesterday. I still not know if “brain zap” is my diagnosis. It is definitely in my head, hits me without warning, lasts a minute. I feel disoriented for a few minutes after.
When it happened yesterday, I was at the gym on the treadmill. I was able to stop the treadmill snd then sat down on the belt for a few minutes until I felt stable. I go to a gym at a local college. None of the Generation Z students paid the slightest attention to me.
For me, it’s not an electrical feeling. More like paralysis.
I don’t lose consciousness or have vision issues.
