I have had tingling, numbness in my right leg for 4 months, normal EMG, not any significant results on MRI, slight tear in a disc and some spinal stenosis on L4 and L5 vertebrae. Haven t had a test for diabetes, they did a blood test last Oct, normal range, is there any chance I could become diabetic this fast and not know it? no significant thirst or other symptoms, but my feet are very uncomfortable in any shoes since this problem began in jan.
