Every once in a while I get a severe pain that localizes on one side of my face at a time. It effects my temple region, around and behind my eye, and into my upper jaw and makes my teeth ache. I find no relief from off the shelf pain relievers or from sitting in a dark room. One time it kept me awake 5 hours straight(12am-5am approx) before I actually fell asleep from exhaustion. The pain was extremely painful and hard to cope. I was wondering if this is a cluster headache and if so, is there any way to relieve the pain? I also had a minor one last night and when I woke up this morning, for some reason, both my eyes hurt a lot. Not like the normal "arg it's bright" pain. More like getting soap in the eye type of pain, just without the irritation to cause tearing. I also couldn't see completely straight as if I was almost intoxicated, yet I haven't touched alcohol for a month or two. It was like my eyes were crossed and I was having difficulties un-crossing them. Could this be associated any way with my headaches? Thanks!
