<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am having tingling to numbness on my left side.I have had a stroke in 2008. I found I had a hole in my heart. Dr Roberts from Miami inserted a closure, but found I have pulmonary arterial hypertention. but the tingling is getting in feet, arms and legs, and they turn blue on the end.  <response>: Hi welcome to Chat Doctor. I understand your query and concern. Elevated pulmonary arterial blood pressure in your case needs good control. I advise you to have a baseline 2 dimensional echocardiography, ECG and lipid profile to assess the basic cardiac reserve of your heart, CT Brain. Restrict the intake of salt to less than 6gday. Regular physical exercise in the form of brisk walk for 20 min a day for 5 days a week is pretty useful. Chat Doctor.
