Even if your diabetes is currently well controlled, you should continue taking your medication unless your doctor advises stopping it, as it helps prevent future complications. Pain in the left leg after consuming sugar may be due to nerve or circulation problems related to diabetes, so you should have this evaluated by your doctor.

Poor sleep, palpitations, and chest pain may be caused by anxiety, stress, acid reflux, thyroid problems, anaemia, or heart-related conditions. It is important to see a doctor promptly, especially if the chest pain is severe, persistent, or accompanied by breathlessness, dizziness, or sweating.
