Hi, Over the last several months I have been experiencing chest pain and shortness of breathe. Recently it has also been dizziness and nausea. I have had tests done such as numerous EKG's, blood work and chest x-rays. I have also had a CT scan of my head, echo, stress test and PFT. All came back normal. Do you think this can be anxiety? Can these symtoms happen everyday and be extreme? Should I worry abot my heart?
