I have been dealing with PCS for about four months now. Recently I have noticed a change in what I describe as the 'weird head' feeling. I now have difficulty talking, in that the words seems to reverberate inside my head, and also make me nauseous at the same time. In fact, for a short time, I thought I was getting better. Now I am feeling much worse, and the sensitivity to lights and sound is also worse. (I drove home from work tonight wearing my sunglasses - the glare of the oncoming headlights was so difficult to take!). I think this is a direct effect of employee health increasing my hours up to 6/day. Has anybody else had this happen?
