Hi, I would suggest continuing your antihypertensive medication for blood pressure control and preventing complications. Your blood sugar levels are actually normal, but I would suggest a more accurate test like the glycated hemoglobin to check for your sugar levels for the past 3 months. And there are also a lot of causes for tingling sensation in the hands and feet, which includes, but not limited to diabetes mellitus, dietary deficiency of Vitamin B, and musculoskeletal problems. I would also suggest weight loss by regular aerobic exercise and a low fat and high fiber diet as these are proven to lower your blood pressure on top of the medications, and in general, lower your risk of atherosclerotic disease like heart attack and stroke. I recommend a check-up with your doctor (even as an outpatient basis) for further examination and proper medication prescription as there are different drugs that fit a particular profile. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Daryl Derick B. Dizon, General & Family Physician
