Sometimes I wonder if this whole PCS thing is all in our heads. Some of the symptoms are completely legitimate (dizziness, tingling, etc), but I feel like that fact that we are all on this forum and have done a lot of research into PCS, we may be actually feeling exaggerated symptoms because we are so aware of them. Things like brain fatigue, tiredness, etc are all part of daily life. I think at times we may be just reaching on these symptoms and over-exaggerating them.
