Hi I'm 27 years old. I am 5 3.5" tall and weigh about 136. Back in July I went into the hospital for heart palpitations. My heart rate was at 122. They did an x-ray, EKG, and 6 different blood tests. Everything came back fine. My tsh level was at 6.26. They said that it's just anxiety. About a few weeks later, I went back into the hospital for heart palpitations and they did another x-ray and more blood tests. The x-ray came back fine along with the EKG. My tsh level this time was 8.1. They said it's just anxiety and sent me on my way. I since then have had, an echocardiogram, which came back as I have a trivial mitral and tricuspid valve regurgitation. They told me that it's nothing to worry about. I've also had a 24 hour holter monitor and that came back fine. I've had an MRI without contrast because I've been complaining of dizziness, and that came back fine. The doctors just keep telling me I have anxiety. Right now, I feel like I have tingly sensation in my left arm and leg and I am weak and dizzy. I also have pressure near my heart and my left shoulder blade hurts. My blood pressure is also 102/72 and my pulse rate is 74. Could all of this be anxiety?
