Tingling in both feet and legs.

Hi! I've had constant tingling for 19 months now on both my feet and legs and in some occasions my hands to. It started in my toes but now has spread up. My first complain was the pain in my upper abdominal. The doctor gave me esomeptazole  and domperidone. And two weeks in taking them was when the tingling in my toes started. I complained again about that and the doc said it wasn't the meds fault. Now I don't know. Help. I've seen numerous doctors and they don't seem to care. I've had several tests done too. A1C was 5.6, ANA is negative, Anti-ENA is negative, calcium/sodium/potassium are all in range, ft3lll/ft4ll/TSH are in range, emg is normal, ncv is normal, Sympathetic Skin Response result was "absent sudomotor response" I sometimes have pains on the skin of my legs. What's happening? Additional symptoms are dizziness (but I don't get enough sleep, staying up late), sometimes pain in my knees and feet, tiredness. Thanks in advance.
