I had a horendous series last light, with one event being the absolute worst I have experienced. But what is troubling me now is the after effect I experienced. the left side of my head, fromthe top on down to my lower jaw bone was numb. I mean really numb, numb as in nothing I have felt after seeing the dentist. I am needind to know if any one else has had this happen and also if the have been any studies on the effects the cluster headache has on the affected nerves.
Anyone have some info please let me know.

Frank,

Dennis is of course correct about seeing your Doc if things change.

I will add that: Yes, the top/side of my head is numb after a true K9-10 but mine stops just below my ear even though my upper jaw is very much a part of the pain during a hit. Generally the numbness fades away after about 2-3 hours for me.

Now I've almost forgotten that feeling since I learned to use high flow O2 - no more of the huge monster hits these days. 

As a side note - Zomig nasal spray suddenly kicks ass for me when I use O2 while I'm waiting for it to kick in - didn't work well at all before.

Most of the time, HIGH FLOW O2 alone works wonders. If it feels like a real killer, I use a spray and hit the O2 jug again - presto!
