Hello. I'm not a medical professional, just the parent of a kid with diabetes, and I'm a proponent of checking with your doctor if you have concerns. Based upon your scores, though, you are well within the normal range for both tests. 70-99 is normal for fasting, and 70-145 is normal for postprandial. I don't think you need to be worried about lowering your blood sugars, unless your symptoms change.
Nothing your levels are great.
