I feel our brains are so sensitive that anything minute can cause symptoms which makes sense because its injured still.

I was feeling good about two weeks ago then decided to go hiking! Then after that the headaches became worse!

Stress can make it worse, food, light..anything..I guess depending on your body. My headache is constant but I've been trying to pay more attention to when I feel better and when I feel worse and writing it down which can give you more insight into your own specific injury.
Good luck .
