I see patients all the time with this. Fix it.........Cortizone is temporary if it works at all. Tiny incision basicaly 2 stitches. Pain will be gone and function back. Thickninig of the tendon is the cause and all they do is free it. Think of it as a knot in a rope. The knot goes throung the pully and gets caught. That's why you have to force it back. Local freezing and approx. 15 minutes and done.
