Hello Doctor Gopi A: I can feel my heart pounding in my upper body all of the time, but it gets worse when I lay down, it is now 3:12 am, and I am still up, because I cannot relax when I do lay down. My upper body feels like a time bomb about to explode at any moment. I just know that if this continues something serious will happen. I have had all types of test, and been to numerous cardiologist, and they all say they cannot find anything wrong with me. I have had heart monitors, ECGs, MRIs, catscans, threadmill test on threadmill and with the injection they give instead of the threadmill, ultrasounds, overnight observations, etc. When I lay down, I can feel my heart beating more in my ears, chest, head, and arms, and intense throbbing, like soldiers marching in my body. I have also gone to a psychologist that put me on Zanax and Cymbalta, which is not helping at all, she said it may be anxiety, panic attacks, and severe depression. The Zanax is only .25mgs, they tell me that is a child s doseage, I have been taking this same amount for over a year. Sometimes i take 2 and feel a little better, but then my prescription cannot be filled on time, so I just suffer. Please give me an idea of what you think is going on. Thank you very much.
