Hi, I've had this for a few months now and it got a bit better and now it's getting worse again. I was having chest pains back in October and went to hospital to get checked out. I had blood tests, chest x-ray and an ECG which were all fine and I was told it was just a muscle problem and anxiety. I am 20 years old with no known history of heart attacks but I suppose i could eat healthier and exercise more. The chest pains are still there but now it has spread to my middle/upper back and shoulders and arms and it hurts so bad I couldn't sleep last night and makes me feel sick because the pain feels like its straight through y body from front to back. I'm so scared that it's early warning signs of a heart attack or something awful like that. I don't know what could be causing this pain and it scares me because I can't see a doctor at Christmas. Can I trust in the ECG, chest x-ray etc being accurate when they show nothing is wrong? What do I do? I am in so much pain the top half of my body hurts so much.
