Consider yourself fortunate that your symptoms are subtle enough that you are entertaining the possibility that they are all in your mind!

I have always been pretty honest with myself, and tend to have a fairly scientific outlook on life, and I am certain not all PCS is a figment of peoples imagination.

Science and medicine, despite being truly amazing in everything they can do for us, can sometimes suffer from hubris and unjust skepticism. They have a tendency to doubt anything they can't measure definitively. The brain is likely orders of magnitude more complicated and sensitive that any model or instrument they may try and understand it with currently. The physical orgins of PCS likely lie in that disparity. Perhaps in 500 years they will be able to precisely measure and diagnosis your symptoms.

When I was a teenager I remember complaining to my mom that I was having trouble sleeping at night because my legs felt restless and itchy/crawly. She thought I was crazy, as did everyone else I mentioned it to. Fast forward 20 years and now they have a name for it.

The fact that we all have a shared/collective experience here is enough validity for me. One day science will catch up.

Having said all that, I'm guessing PCS is a dynamic between the psychological and the physical. In many cases it probably lingers on longer is physically justified. We get used to it, in a strange sort of way, and have had our confidence and enthusiasm shaken to the point that we are not ready to give it up. If your symptoms have subsided to the point where you find yourself pondering whether it's in your head or not, I'd say the best think to do is "let it go", so to speak, and consider yourself a 100% again.


After all, even people who have never had a concussion get headaches and have off days when they just feel spacey.
