What are these symptoms?

Hi so I am 17 and recently I have been having weird symptoms. I've been having chest pains, nausea, and body aches (back, side, legs, feet (top and Bottom), neck, jaw, cheeks -everywhere!) also I have been having headaches. I called a doctor and told him my symptoms and I told him that my pressure is perfect. I called because I thought it was a heart attack. He said that it was a panic attack. I have had panic attacks with this every night because I think that it's a heart attack before going to sleep. More recently I've been having a burning sensation that last for a few second on the top of my left foot below the toes. I also have been having extreme body pain which becomes unbearable. I wake up with extreme body pain. To describe the aches, it's like flu aches. Im scared. What is this?
