Hi, I have been diagnosed Mitral Valve Porlapse and Autonomic Dysfunction. I have seen both my family dr and contacted my cardiologist . I have a follow-up in 3 days from wearing a holter monitor . I have had an upper respiratory infection that has been difficult to get over and makes me feel even worse than usual. I have been having pain in my neck, and actually felt cramping in my heart one evening. Could the stiff neck be related to my heart at all? I am on antibiotics and steroids. I actually have been having a head rush/pounding feeling too, which is not normal for me. Usually upon standing my BP will drop. I feel like my condition gives me a constant struggle, yet drs act like it is nothing. It can be so frustrating, and now things are different. Your toughts?
