Thanks for using the forum.
Neuropathy is usually a symptom of blood sugar that has been running above the normal limits. You have not had any abnormal fasting blood sugars and your one time elevated A1C could have been attributed to the after effects of surgery. A1c results after surgery can be unreliable due to blood loss, blood transfusions, and anemia. If subsequent levels have been within normal limits, then I would think it is unlikely that you are experiencing neuropathy due to diabetes.
I have to caution against stopping/changing doses of medications with out the supervision of your doctor. I would recommend you have a conversation with your doctor about the concerns you are having. Ask if there is any link between the medications that you are already taking and your symptoms. If you want to make a change, ask your doctor about alternative medications.
I hope this helps.
