I should point out that I haven't been formally diagnosed with PCS. Since my brother went through pretty much the same thing as me and due to my history of mild anxiety problems, the professionals I'm getting help from are treating the concussion as a trigger rather than an underlying cause. I personally feel quite different since the concussion and kind of know deep down that it's the cause, I hold a little hope though that it's all psychological. Who knows, who cares, the important thing is getting better and that's happening slowly but surely!
