I have had palpitations, dizzy spells and sharp chest pain since my early 20's. However, the pain has changed. instead of the shortness of breath, dizzy spells or pressure on my chest being a random occurrence, it seems to be all the time. My heart beats fast all of the time, my glands are constantly swollen, the dizziness and lack of energy gets in the way of everyday responsibilities. I have had some tests done ( stress test, wore a monitor for a week, x-rays) and I have been to the E.R. for a panic attack (didn't know that's what it was a t the time). My doctor was the only one who reviewed my test results, told me - it was just stress and prescribed me xanax. I took them twice and it didn't help, nor did I like how i felt on them. I get numbness in my legs and arms (worse if I drink alcohol), migraines, tense and can be relaxing but feel my heart racing like i am running. I know it is more than stress, its obvious to me that it gets worse sometimes do to stress but I am working two part time jobs to put myself through school and do not have health insurance. Any thoughts on what it could be?
