text_1: This morning I saw a 65-year-old woman with diabetes, hypertension, elevated lipids, and coronary disease.  She has chronic low back pain, two surgeries, can hardly move.  I referred her to a neurosurgeon who talked about implanting some sort of nerve stimulator.  Not a transcutaneous nerve stimulator, but something implanted.
