For the past few weeks I have CONSTANTLY felt anxiety symptoms. My chest constantly feels very pressured, and shortness of breath is often accompanying it. My legs and arms get tingly, sometimes they twitch and have pains. My chest also burns sometimes. I have high blood pressure but medication has kept it in check. Twice now I have gone to the hospital and all tests come back saying my heart and insides are healthy. Normally when I feel an attack coming I can calm myself down but for the past week it has been literally impossible. Also, today a new symptom started where my neck and head feel full of pressure. Its keeping me from going to school consistently and I'm really scared its something very serious. I have a pretty high pain tolerance, but this is unbearable. I start medication tomorrow for the first time, and I'm scared that I won't react well to them. If anyone has had all of these symptoms or has any advice, please let me know.
