Dear sir/madam i can understand your concern. in my opinion you should make sure that with pump or with injection you should manage to take the total dose required in a day. your sugars not coming down even with lots of injection,There might be some problem in dose of insulin or if insulin is not maintained in proper cool condition it will lose its potency. Acidity and aching legs might be due to uncontrolled diabetes. i suggest you to see your diabetologist and readjust your treatment. Hope I was able to help you. If you have any further question feel free to write me back. I will be happy to help. Take care. Best Regards. Dr Vamsi Krishna Consultant Diabetologist Apollo Hospitals
