*UPDATE*

I forgot I had posted this! So here's an update.

The MRI on my head and ECG on my heart came back normal and doctors have diagnosed me as 'unknown'.

I think I am learning to understand what causes these episodes and that is when I knock my head. I try to avoid this as much as possible. The slightest hit or tap can cause me to have one of these episodes, which happens about 2-4 days after I've knocked my head.

I'm currently not being investigated further by the hospital. I guess it's just an anomaly that I have to be cautious of.

If anyone else has the same or similar episodes that I have, please share. I would like to know I'm not alone with this!
