Hi There and welcome. You are not alone. I went through 8 Drs. to convince me that I wasn't dying of some tumor or cancer. I had Mri's ct's and tons of blood work. I wore a heart monitor for 4 days because my heart would have an irregular heartbeat. When I first started my panic attacks I called 911 on a semi regular basis. I had tingling in my buttocks and arms and now have them down one side of my face. It is tough trying to find a med to help you get through to the other side of panic. I understand your pain and fear, I've been there to. Keep trying to breath, if you feel an attack coming on open a window and get fresh air, run some very cold water to splash on your face. Do anything to get your mind of the symptoms. We are here for you and you are not alone. Janis
