It's been about 3 months now, I started with heart discomfort. I went to go get checked with a doctor he did blood work(ckd: kidneys, thyroid, blood count,stress test, he even checked my lungs everything came out ok. I just get this feeling of shaking inside of my upper body especially my left upper body. I get multiple symptoms that include: shaking of hands, weakness, low energy, chest pain that somtimes goes towards left shoulder and left side of neck, a hot rush that starts upper body a goes down to my legs, feeling of fullness in both ears, pulsing under left breastbone, abdominal pain, muscle stiffness: both arms and right leg, shortness of breath choking sensation, feeling of not going to make it anymore like going to have a heart attack or somthing? It's just so hard to belive it's axiety with so many symptoms. I just want a better understanding of axiety and can it really make you feel all of this?
