My father in law has Copd and has been in and out of the hospital since December. He has only seen Dr. Roman once. We went a month without blood pressure meds. They gave him oxygen to use at home with his oxygen levels at 97 or better. He has been overusing it and now has what looks like burns on his cheeks and nose. The office was supposed to schedule an appointment with a neurologist and that was three weeks ago.
