Worldofme - It is crazy and yes always nervous, then mad at myself because being nervous makes it worse. The thing is it hits out of no where and then you cant help but feel nervous. I am constantly questioning, what if this is something and I ignore it, what if it isn't and I go to the ER again. Ugh. So far, I ignore it but sometimes it lasts hours. As far as the cost, $5k is ridiculous. I don't have that kind of money on top of all the copay's, scripts, etc. Sad world we live in when someone makes a good living and still cant afford to pay medical bills.
