I have recently been to the ER almost 4 times over the last 6 months, my concerns have been chest pain followed by palpitations and vice versa. My tropnoin levels were less than 2. My doctor completed a stress test, ecg, 2D echo and everything came back normal. My blood work is also normal, with slightly high HDL. I have also completed - 24 hour holter test, and it came with no abnormality. Now i have headaches, and dizziness and pins and needles across my arms and legs. I am unsure if these are anxiety related symptoms (or something sinister). Thanks for your assistance with this.
