Hi, I am going through another battle of panic. It's alot different than my past experiences. I'm having frequent attacks right after each other. It's not passing - this is all happening at night. I do get attacks during the day, but this awful stuff is at night. I wake up detached, feeling faint, dizzy, anxious, heartbeating, chest pain, (which is all familiar to me) but now, I have this burning sensation in my arms and legs that is rather painful. I have a closed throat and really feel awful. I am new to the area I live in and have seen a dr. I told him of my past exp. but this being different they put me on a light beta blocker due to my heart racing so much and I made an apt. with a physc. but what do you think? I'm jumping out of my skin hear is it panic? Or heart condition causing panic symptoms w/ additional scary - also anyone on meds. I haven't had much luck in the past, but am desperate. Dr. gave me Lexapro (w/ the heart med) nervous to take>>>>
