Pain in my chest, my breathing was a lot of pain, my head hurts, and the two sides of the neck veins, which simply does not have the energy left hand, I have tried many doctors showed a lot of heart, but I did not get in any problem, all the test normal, but I think I'll die if this continues. Please tell me what I can do. My chest hurts and I can not stand this. Please help me.

Hard for us to give you suggestions when you apparently have been to a number of doctors and the tests are normal. Have you been to a Neurologist? Where are you located?

You need better heart tests, and you need tests on your jugular and carotids such as MRA.
If you can afford to go to a big city teaching hospital, please go! Or even a country known for good care.

What is the blood pressure when this happens?
Are there issues of extreme stress?
