I have had for last three or four days had shortness breath, excelerated pulse, trouble swallowing, headache with pain localized to the front region. Tingly numb left arm along with felingice cold inside. Chest pain that comes and goes and the shakes, nausea, dizziness, blurred vision or seeing black and spotty, lack of gearing in both ears to this almost roaring sound... Any ideas what this could be
