i have noticed for the past year i have been experiencing a feeling of a single heartbeat that starts in the middle of my chest, it seems almost like a spring effect feeling, that will run through parts of body and end in my fingertips--i feel this at all times lying down, sitting up, standing walking etc. i try to explain it as a "boingy feeling" like a spring being pulled and let go of, what you would expect it to feel like, i have searched for someone else who has this problem and have come up empty handed. i have ruled out most diseases thru the computer and have a very hard time explaining it to doctors. i do not have any pain when this happens, it comes and goes from day to day, days that i do have it, it recurs many times throughout the day, not sure if the headaches are related to this or if it may be caused by my antidepressant celexa, klonopins for anxiety do not make it go away (they make it more mild) i had a doctor put me on xanax for anxiety and that seemed to keep it at bay, most doctors will not prescribe xanax, and since i can't describe this i am unable to find a cure or even what it is. if anyone has similar symptons please advise, feeling very frustrated-which does not help with my anxiety or depression
