Dr. Trenhaile was absolutely outstanding. Explained the issue in understandable detail and indicated that surgery is the last resort and provided a plan of action to resolve the issue with physical therapy. Provide an injection that provided immediate relief and has allowed me to work through the prescribed physical therapy.
