hello Janet Treash
welcome to healthcaremagic
from the brief history you have given us on your surgery, i agree with your doctor that the pain will persist because the ankle has been operated many times and there has been correction of tendon and ligaments, there will always be presence of stretching of the surgery site and due to multiple surgeries there is a higher chance of developing adhesions which can also cause the pain when thet stretch.
i would suggest continue with the treatment that your doctor has prescribed for you and physiotherapy
may help with reduction of pain and help in reducing pain on movement of that ankle
hope to have answered your query.
wish you a quick recovery and be strong takecare.
