Feeling light headed dizzy tingling in extremities flushed have normal a1c?

Hypoglycemia: It seems you have diabetes, if you are knowledgeable about your hemoglobin a1c. The symptoms you describe could be due to low blood sugar (hypoglycemia), produced by a diabetes medication taken with too little food. Your a1c would be normal if you have frequent low blood sugar episodes.

Need to examine: It appears that you are diabetic and could have neuropathy. It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see your doctor. Wish you good health!
