First of all, don't take these quick sharp pains too seriously. Have any of you heard of "ice pick headache?" You can Google it on the web. It's sort of a form of migraine and can occur from time to time, anywhere in the head.
They have just about knocked me out now and then because they are sudden and quite painful but they are quick and I can go years between bouts. Usually I get a few pains, then nothing more for weeks, months or years.
During the middle years I got a lot of typical migraines and before that, plain old bad headaches, so I am a "headachy" person.
Again, don't focus too much on this and if your vision is not affected at the time and you otherwise feel good, you are probably absolutely fine.
I get these ALL the time and they totally freak me out and I end up panicknig and the pain worsens and then I get dizzy and the pain spreads, totally making it all worse than the original pain in the first place!!! I think a lot of it is to do with me clenching my jaw, I do it without realising, and in my sleep too. The pains I get are in my temples and are like shooting stabbing pains. I also get a weird pain right at the top of my head which feels like somebody is tightening a vice around my head. Before I found this site I thought that it must be something SERIOUS, now I am thinking it is all down to panic.
I use to get these a lot also, but havent had one in quite a long time, now Im getting more panic attacks on my chest. But when I do get them, It hurts a lot on the side of my brain but it last only like 10 seconds.
I can sure relate!!! I hate these, And with us panic people we think it is a tumor or aneryism or something awful like that! then we panic more! what a horrible cycle it is. when this happens I just take a deep breath and try not to think negative and it goes away.
