Hello sir.....my dad is 64 years old and has burning sensation throughout his body since few months. We have visited lot many hospitals and doctors but none could heal him. He is diabetic, injects human mixtard before breakfast and dinner. Previously burning sensation was limited to abdomen, now it has spread over whole body. Abdominal ct scan was done and everything is found to be normal. Sugar is under control. So sir please advice me what should I do to cure him of burning sensation .
