My husband is 66. No high BP or diabetes. In great shape but for some confusion when driving, I.e. losing his way in a medium sized city he’s riven forever. This for approximately one year. In the last mont I have notices a constriction of the fingers on his left hand when he has his hands to his side. I’ve mentioned both to him but his answer is to ignore both conditions, other than let me drive most of the time. Could there be any connection between these two seemingly unrelated symptoms?
