Anxiety is a common symptom of PCS. It is likely triggered by environmental issues.

How do you respond to the anxiety events?

Have to tried to identify any environmental or behavioral issues that may precede the anxiety event?

Even though your other PCS symptoms have resolved, you may need to take steps to reduce the likelihood of anxiety issues.

I still struggle with anxiety from time to time. I have a blood pressure med to take when my blood pressure spikes during an anxiety event. It makes a big difference.
