Thanks. I had already found the information you provided on websites dealing with blood pressure and cardiology.
I wonder if the following additional symptom may be related to the blood pressure finding: I'm chronically kept awake at night, not only by arthritis pain, but also, increasingly, by severe numbness and tingling in my hands and to a lesser extent in my feet. I have no history of diabetes, so this is unlikely to be diabetic peripheral neuopathy. But I wonder if it and/or the BP finding could be indicative of Peripheral Arterial Disease? But I have no history of elevated "bad" cholesterol levels and, in fact, my "bad" cholesterol level is typically low while my "good" cholesterol level is typically high.
