I am only reflecting on my own experience, the light and noise sensitivity, headaches, fatigue, low mood, hypercusis were solid for about 3 months in my case, they only reduced with a medication called Cymbalta.

I imagine headaches, light sensitivity etc are temporary for most people with PCS, but in my case I needed medicinal help. I still have headaches, fatigue and sore eyes 8 months on, so goodness knows how I would be if I hadn't taken medication.

I had a really tough day at work today, worked 8-6 and drove about 250 miles starting at 7am. The result is a headache tonight that will not go away despite the Cymbalta, but not for much longer because the Imigran I have taken will eradicate it.

So things are going away in my case - but not on their own!
