going to the GI

So I finally saw my regular doctor who said there was nothing more she could do & sent a referal to the GI dept. After a week they called me & were going to make me wait 2 months to see them. Hell no. So I got an appt. for the 17th (July). They are doing an enscopy(sp?). A tube w/a camara thet they stick down your throat to your belly, to see whats going on. I am friaghtened ... cause they haven't even talked to me, let alone seen me. Is this typical? I keep wondering if there's something wrong with me heart... Still having the tingles in my limbs... I wish this would stop & I'd have answers
