Cold feet

I have been diabetic for about 30 yrs. Take Metformin and Glipizide. My A1C just in the last year went over 7. My Dr wants me to add Trulicity but the cancer warnings scare me. Just this past weekend I started having cold feed now concerned about neuropathy. I am obese and struggle maintaining proper diet but I feel like sometimes my Dr isn’t listening. Do I need to see a endocrinologist or neurologist?
