Alex,

I suggest you relax and stop trying to figure this out. Your symptoms may or may not be PCS. They are so varied and atypical that they could be just a cluster of odd symptoms. There is not much you can do for PCS, especially when the symptoms are so mild and infrequent.

If any of your symptoms were more frequent, then there might be things to do to help with them.

If you start having memory and cognitive difficulties, then it is more likely you have PCS.

You could also keep a journal to see if you can find a link between triggers and symptoms.

Your last statement about living healthy and resting is your best bet.
