Quick Question:

Recap: First concussion Septmeber 3rd, had all the standard PCS symptoms, no anxiety, recovered after 1.5 months.

Second concussion received after a month and half after being symptom free. Had all standard PCS symptoms for 3 weeks.

After 3 weeks i started getting high levels of anxiety and i am pretty sure i even had a panic attack. Over the three week period i took Xanax three times. Had an MRI and CT scan done. No longer taking anything.

Since my anxiety and panic attack three weeks ago, i have been experiencing the following NEW symptoms that were never present in my previous recovery:

Extreme leg weakness and uncomfortableness especially at night
weird sensations in my entire body
overall muscle fatigue
poor circulation
muscle twitching all over
feeling of heartbeat in head

Now, since Friday, i have been getting better sleep and my anxiety has been relatively low. I also have been much better with my Head fog and grogginess however i my legs are still extremely weak and anytime i rasie my heartrate, i can feel my heartbeat in my head.

Why did i not experience this in my first concussion? If these new symptoms are caused by anxiety then will they go away as fast as they came?
