Hi,

I had a concussion almost 6 months ago, and my dominant symptoms left remain my vision.

During the first months after the concussion, i had some trouble sleeping. It got much better for a few months of recovery.

However, 2 days go, the insomnia suddenly came back, this time much more severe. And I haven't slept for the past two days. I feel tired. However, it seems like my brain can't just go into sleep mode. The back of my head feels tingling.

Is it normal for concussion recovery, especially when most of my symptoms have gotten much better?

I am taking several supplements to help my recovery, including 5-htp, L-theanin, and Magnesium. It appears that my sleep was improved for a couple of months. A sudden symptom coming back scares me.

Thanks,
