Hello doctor! I have symptoms of the disease, which is a sudden feeling of cold in my chest, discomfort, shortness of breath, convulsions of limbs, heart palpitations and the feeling of fainting and very tired. I went to many doctors and had ultrasound scans, but nothing was found. So what does the doctor tell me about the signs above and how to treat it? Thanks for the advice doctor!

Doctor, I often worry, every time something happens, my heart beats fast, my blood pressure increases, I sweat, I talk a little, my hands tremble. Sometimes I have angina and anxiety, can't concentrate on work. Especially when someone notices that my hands are shaking and I am insecure. Please consult your doctor.
