I Have Diet Controlled Diabetes 2. Last Blood Sugar Reading

I have diet controlled Diabetes 2. Last blood sugar reading in August was 46. I have had no symptoms until now. In the last few weeks I have experienced tingling in the feet and lower legs, but not painful. I saw the practice nurse and told her. She checked my feet pulse and said both were very strong. She said it was most unlikely to be connected to my diabetes, but that if it continued I should visit my doctor. Any thoughts?
