It sounds like you are getting the eye droop? I used to get those once in a while but not too much lately. Do you do stuff like press on your eye or slap you head? I really try to avoid those things. Many CH people have squished their eyes to heck. As for shadows, they def can vary and some are so strong that it's not far off from attack level pain!
Hang in there warrior, I too had a huge set of attacks last night and I am trashed and full of shadows today.
