Jola - see if you can find a physiatrist - a rehab physician. I worked for a group here in Kansas - we saw many people with neuropathy combined with gait imbalance due to the neuropathy. They can test you to find the exact area causing the neuropathy, they then work with rehab therapists (PT/OT) under their direction to provide the needed actions/activities/exercises to see if a change can be made with the tendons and other problems that you are mentioning. Sometimes orthopedic physicians do not think of a simple referral... Physiatrists are trained in physical rehabilitation/pain management (one of the few who are) as well as an extensive knowledge of nerves and muscle grouping as they often work with stroke victims to car accident victims to regain their life... I wish you the best
