It can take weeks, months and sometimes years to recover from an adrenaline storm. You don't need to feel anxious for your body to be reacting to the anxiety you had last week. When chronic adrenaline flows sit on muscles unused, they twitch, hurt, feel weak, shake, etc and so on. During my last attack I could barely shampoo my own hair. My arms would get so exhausted in just seconds. My legs were giving out on me...they hurt...hypersensitive to touch. My startle reflex was absurd. I twitched everywhere...hot spots for days. The self testing only made it worse. So, work on your anxiety. Accept that you are ok...if not you will continue to suffer. Do something different. Accept that you are well. Work on your anxiety.
