Your rapidacting insulin, Humalog should then be administered before meals and your dosage must be changed according to your pre-meal reading and what you are going to eat. You must consult your doctor and dietitian again to assist in improving your sugar control. The pain may be related to your uncontrolled sugars or it can be electrolyte disturbances or neuropathy - there are medications available to manage this but you need to consult your doctor to determine the course.
