I wish I should write about some sport injury or even a heart condition. Instead I have to ask about encephalitis. Actually I was not diagnosed yet, but all the symptoms are here. I had varicella problem followed with headache, nausea and photophobia. I guess all that is left now is to go the doctor for the confirmation of the diagnosis.
And you should do that as fast as possible. I assume that you already know about the possible complications that might occur and sooner the treatment begins the better chances you have to avoid some of the very unpleasant consequences this condition have. And I hope that you will not be the one that suffers because of the encephalitis.
