Hello. I am a 31 year old female recently diagnosed with MVP and sinus tachycardia. My doctor says that I should not have any symptoms from this and has prescribed Wellbutrin for anxiety attacks. I have recently been having headaches, ringing in my ears, lightheadedness, dizziness, chest pain and a fast heart rate. What should I do. I am scared because I have a 2 and 4 year old that depend on me. Any help would be appreciated. Thanks.
