Hi Chris and welcome to NeuroTalk! You might want to also post in the General Health Conditions Forum http://neurotalk.psychcentral.com/forum2.html. You might get more responses there.

It's scary when things happen and there's no explanation for it. Sometimes our own anxiety over the unknown will cause our symptoms to become exaggerated. I know if I'm anxious about something I get hyper-aware of every little symptom I have and that just seems to make it worse.

I'm sure others will come along and welcome you to the site and give their own advice. Sometimes Sunday can be a slow day here. Have a look around the forums and see if there are any posts that might be of some help to you. You're not alone. There's lots of very caring and supportive people here.
