I found myself having symptoms like a disorder of the autonomic nervous system: weak limbs, pounding heart, nervousness like fainting, especially having to stretch out to take a deep breath to feel comfortable. This phenomenon is happening more and more often. So, doctor, tell me if my hands and feet are weak, my heart is pounding, I am nervous, and I have trouble breathing, is it a disease of the autonomic nervous system?

I have symptoms of dizziness, weak limbs when moving, shortness of breath when lying down, rapid pulse, difficulty sleeping. My blood pressure is normal. I have been like this for two days, taking pain relievers, it helps and I can sleep. So the doctor asked me what is the disease with weak hands and feet, shortness of breath with a fast pulse?
