One of the first joints to suffer is the shoulder.Most of the literature and research documents I have obtained state quite clearly that Wikipedia reference-linkfrozen shoulder in diabetic patients, if due to collagen deposits and calcification, does not resolve as it does in the general population. Frozen shoulder is a generic term and it depends on causes it. If it is due to strain e.g. in women carrying a heavy handbag on the same shouler for many years, then physio and PT will resolve it in 9 cases out of 10. But if the cause is solidification of the joint capsules and tendons this is often irreversible. Given time, the symptoms will reverse themselves naturally, although this process frequently takes a year or more. Anyone with this problem should consider that letting mother nature take its course may be preferable to surgery and other drastic alternatives. One should consider that doctors sometimes cause more damage with intervention and are frequently not successful. Gentle excersize and stretching during the "melting" phase of this illness will hasten improvement.
