I know that nobody can make a diagnosis, but I need some advice or opinions.

For a while now I've been getting these sharp pains in my head, hands, arms and legs. It almost feels like a brain freeze; they last probably 10-30 seconds and they're totally random. I don't usually get headaches and when I do they aren't really that bad. But today I have a headache and it also feels like there's a lot of pressure built up inside. I do have high blood pressure (at least I did when I was pregnant), so maybe that is playing a a roll in why I feel pressure. I was wondering if this could be a brain aneurysm or just a weird headache? I won't take your advice or opinions as a diagnosis, but if you could tell me what symptoms you had (if any), that would be very helpful. I'm the biggest worry-wart I know, so needless to say I'm just a "tad"-bit freaked out about this. I'm scared of dying... especially such a sudden death from a silent killer.

Please, please reply.
