Shadows are what we call low level hits, say up to a K3 or so that can hang around for a while, and or precede or follow an attack. They are also a feeling almost of dread that I get for a while just before a hit. Kind of like seeing the shadow of the school bully at the corner of the building. You know he is just waiting to pounce, but you can't really see him.
The tension type of HA sounds to me more like allergy, but I'm certainly not a Dr. The only thing I have in common with the medical field is my bad writing.

Wht you are experienceing around your eye could be shadowing. Not everyone experiences CH in the same way. Mine will occasionally throb, especially the lower K hits, but always around the right eye and temple, which is where I get my attacks.
As to the variation of temps I have no opinion. I've not experienced it other than the area around my temple will be hot to the touch for a while, but that is probably due to rubbing and pressing on it. Are you trying to stay in bed during a hit? I don't understand how you could. Lying down exacerbates mine rapidly! It could be you are elevating your ody temp through the exertion of fighting the pain, but I don't understand it remaining elevated. It definitely sounds as if you have an underlying problem causing that.
Don't worry about how high numbers your attacks reach. Each of us reacts differently, and each cycle is different in its presentations, and your treatments will vary, so consistancy is only reached by its inconsistancy. Does that make sense? If so, please splain it to me!

The purpose of the Kip numbers was developed by Bob Kipple, one of the founders of OUCH and early participants on this board(recently deceased), in order to have a more definitive way to describe our pain level to our Drs and others rather than just a nebulous 1-10 scale of a frown face or a happy face. You don't get brownie points for getting higher numbers!

; It is as comprehensive an explaination as I have seen, yet is understandable to those who don't have a medical background. It has been very helpful to me over the last few years, and I'll be using it again next week as we start a new school year.
Hope all of this helps.
