Is this anxiety??

I’m 17 and I have bad health anxiety. Rn I’m panicking rlly bad because I keep getting sharp chest throbs on the ride side of my chest. It’s off and on and I’m getting so scared. I’ve been to the doctor before about chest pains and he did blood work and said everything was fine and that it’s caused by my anxiety. Also I used to get chest pains when I was 12 and they did blood work, EKG, heart monitor. Everything was fine. What should I do???? I’m scared.
