First of all, I had two drinks last night (I should have been avoiding alcohol due to PCS but unfortunately the social occasion got the better of me), and I felt a burning sensation at the back of my head? Why would this be?

Secondly, has anyone else found their tolerance for stress has been significantly reduced? I am generally okay day to day now but the moment something stressful comes up I get crippling headaches; I get them a lot at the moment as I'm possibly about to be made redundant.
