Diabetes: legs shrinking, pain from hips down even more extreme at night, glucose levels destabilize randomly, chest pain, jaw pain, what gives?

See a doctor: Chest tightness and/or jaw pain is a heart attack until proven otherwise. Call an ambulance and head to nearest er.

Poor control: Your diabetes is poorly controlled. You have nerve damage in your legs and may have heart disease. See a diabetes specialist asap.

Have it evaluated: A person with chest pain needs to be evaluated and treated appropriately. Multiple possible causes may be: heart attack, esophageal reflux, anxiety, musculoskeletal, pneumonia, pulmonary embolus, and aortic dissection. Have it evaluated right away to prevent potential serious complications.
