Well, In the event as she had not been called and told not to go she decided to go along to the appointment and hope that they would see her and they did.
The MRI has shown that the left joint has relocated but right joint has not due to an obstruction. The consultant thinks the obstruction is a blood clot which given time will reabsorb. She has come away with pain killers and an appointment for after Christmas. I know these things take time but if it does not go back before her next visit it will have been out for 2 months. Not sure if the blood clot can become scar tissue in which case will it ever go back?
