panic attacks are horrible, mine woke from a deep sleep as well. I jumped out of bed my left arm was buzzing I was thinking I must of slept on it but I was sleeping on the other side. My heart felt like it was going to pop out of my chest, My mind was racing and I had FEAR I was so scared I thought I was having a heart attack so I called the ambulance. I was sweating and shaking,racing heart. This all happened Dec. 8 2006, my whole life took a 360 turn, I gave up smoking , alcohol, caffiene. I was so scared it was going to happen again plus I had heart palpitations. For a month after I had severe anxiety everyday evening were the worst, my body was always buzzing, tingling,really scared me because alot of the times it was my left side,chest pains. Felt like I had pins and needles in my scalp, on the side of my nose,my jaw felt like it would go numb for a second. Itchy inside my leg which would drive me crazy if I let it so I would go for a walk and it would go away I found. Your body is just so stressed it mimics all sort of diseases but it's only anxiety and I am really learning to control that plus I take my meds and vitamins and excercise. I am so glad I mad that change I am much healthier and thank god everyday that it all could of been worse. Most of my body symptoms are gone or at least not as severe I still have the odd palpitations, chest pain still some tingling but it doesn't worry me so much like it did because I know what it is.
