Thanks for this. I have been told that people with PCS have raised tension and arousal levels, it seems therefore that coping with stress is going to be more difficult. Especially if you have insomnia and noise/light sensitivity, not to mention all the worry about what the future holds. The stress of the weekend provoked my symptoms (all be it to a lesser extent than previously) and with it the migraine headaches. I thought it was just physical exercise and over exerting myself which caused this, but clearly too much stress is a factor also. Therefore have seen my GP today and got an antidepressant called Cymbalta 30mg, it also helps with neurological pain also. Has anyone used Cymbalta and found it helpful?
