Wrong guess

I guess I can't always be right. After an appointment with my eye doctor it was determined that my last glasses were made as prescribed..Apparently it was all in my mind that it was the cause of my problem with balance. My physical therapist was right. It is no doubt due to weakness. As I believe I have mentioned before, I have used this therapist for various problems in the past. It looks as if it is up to to me to put in the work to solve the current problem.
