I just finished reading the story about John’s wife and great diagnosis of giant cell arteritus. That will be first question when we see the doctor. My husband has experienced jaw pain a couple of times recently and has said he thinks his vision has changed slightly. He has not had headaches. A few years ago, the ophthalmologist notice something behind his eye and suggested that he have an MRI or CT (I can’t remember which). His internist was not concerned with the results at this time. I will mention this to the doctor.
