This is awesome. My doctors at the VA tell me all the time that i am not alone. But i do not believe them. I check my pulse all the time lately. Four years ago i had a cardio cath. to check my heart for blockages and the doctor told me my heart was very healthy. After that they went away, but four months ago out of the blue they are back. Ad stronger than ever. I think that i am goin g to die and have a massive heart attack, go to the Er just for them to tell me not to think about it and i may live with these the rest of my life. I am so relieved that others feel the same thing i feel and get anxious as well. might help me sleep tonight.
