Treatment for Frozen shoulder usually starts with non-steroidal anti-inflammatory drugs (NSAIDs) and application of heat to the affected area, followed by gentle stretching. There is a non-surgical operation called the OAT Procedure. OAT stands for Oolo-Austin Trigenics. The procedure, in medical circles, is also referred to as the OAT-MCD procedure with MCD referring to a medical description of the operation as a Manual Capsular Dissection. Ice and medicines (including corticosteroid injections) may also be used to reduce pain and swelling. Physical therapy can help increase your range of motion. Surgery may be needed for more serious cases.
