The patient has a lengthy, informative consult with the Internist, the warm and affable Dr. Hays. Good news: except for her symptoms and a little heart disease (normal for her age), patient is in very good health. Best news: Dr. Hays is cautiously optimistic that patient's sense of instability and impaired gate is Parkinson's and that it can be medically treated and improved. Most surprising news: Patient shows no signs of acid-reflux and can immediately quit taking Prevacid, the medication she's been taking for several months to treat that.
