I was diagnosed with Mitral Valve Regurgitation and Pulmonary Arterial Hypertension 2 years ago and of course high blood pressure. I am taking Losartan 100mg and Amlodipine Besylate 5mg. I have periods where my face (both sides or one side) is flushed and feels hot. I have periods of light headed, tingling on my face and head. They do not happen all at the same time. I have not been able to find anything that explains these symptoms and my Cardiologist and Pulmonary doctor do not know. Can anyone shed some light on this.
