I Have Resistant Hypertension And Am Taking 40-60 Mg Of

I have resistant hypertension and am taking 40-60 mg of Lisinopril daily for this condition. Over the past 6-9 months I have been experiencing a moderate degree of intermittent dysphagia. No problems with breathing, just the feeling that there is something going on in my throat that interferes with easy and complete swallowing of certain types of food at times. No weight loss or other symptoms that might be indicative of a cancer. Blood and urine labs normal for my age (early 70's). Suspected arthritis but negative for RA factor. CRP normal. Could Lisinopril be causing this by way of angioedema?
