Hi, Was wondering if anyone here has a Descending thoracic aneurysm that is symptomatic? I have been struggling with a PAINFUL throbbing in my chest, SOB, dizziness, fatigue since the end of May. All my heart test have come back NORMAL. the Thump in chest worsens when i lie flat, and i must sleep elevated. I can do very little activity and my head builds pressure when i bend over. The pain is specific to the left side of my sternum about 3" to 4" long, and sometimes thuds through my back to below the shoulder blades. I'm really having a hard time. If anyone has a diagnosis and has these symptoms, PLEASE tell me what tests to ask the doctors for. Thank You!
