I have been to the emergency room three times in the past 8 months. By ambulance. Medical bills??? Crazy... I think that I finally diagnosed the problem through research. Anxiety Panic disorder. My doctor now agrees. Now I am on Zoloft, Topral and Zanex ,if I feel a panic disorder coming on. I had CT's, MRI's, Stress tests, etc....My question is that has anyone ever felt a weakness in their leg or legs, when the attack is coming on. I get very light headed, my left arm tingles and it is hard to walk. Am I just crazy?? I hate this and can't imagine living like this forever. The meds have helped somewhat to alleviate my heart racing. I can still feel it pounding but it isn't at 140 beats a minute. Please give me your thoughts.
