For individuals with shoulder pain and problems, what are the stages of a frozen shoulder, how long do they last, and what can be done to relieve pain?

Frozen Shoulder Stages

A frozen shoulder, also called adhesive capsulitis, is a very common cause of shoulder pain. It causes severe pain and limited mobility. The condition progresses through stages and can take up to two years to resolve completely. The stages of frozen shoulder include pre-freezing, freezing, freezing, and thawing.

Stage 1

Pre-Freezing – 1 month to 3 months

Pre-freezing describes the earliest stage of a frozen shoulder. This is when individuals first start to notice pain in their shoulder. (Soussahn, S. et al., 2024) Many in this stage will first experience the pain at night while changing sleeping positions. As the condition progresses, individuals may notice pain when they move their shoulders, especially when raising their arms or reaching behind them. Individuals may also find reduced mobility in that shoulder and may ache even when not using it. Because motion may be only slightly restricted in this stage, an early frozen shoulder can be mistaken for a rotator cuff problem. (Chan H. B. Y., Pua P. Y., & How C. H. 2017)

Root Cause

A frozen shoulder happens when there is inflammation in the tissue that surrounds the shoulder joint. Although the specific causes aren’t known, immobilization after an injury and other shoulder conditions, like bursitis, may play a role. (Johns Hopkins Medicine, 2025)

Stage 2

Freezing – 10 weeks to 8 months

The freezing stage is the most painful. The shoulder capsule becomes inflamed and can thicken and stiffen. As this happens, shoulder movements become increasingly difficult and painful. (Soussahn, S. et al., 2024)

Stage 3

Frozen – 4 months to 12 months

The third stage of a frozen shoulder is known as the frozen phase, where the shoulder is stiff. The examination finding confirming the frozen shoulder diagnosis is that neither the individual nor another person can move the shoulder. (UpToDate, 2024) With a rotator cuff issue, a patient cannot move their arm normally, but the healthcare provider can. This distinguishes between a frozen shoulder and a rotator cuff injury. The frozen stage is typically much less painful than freezing, but pain can result from simple activities. (Soussahn, S. et al., 2024) Rotation of the shoulder joint is limited, making activities like washing hair or reaching painful or difficult.

Stage 4

Thawing – 5 months to 2 years

In this phase, the shoulder joint capsule becomes thickened and stiff but gradually loosens with time. (Soussahn, S. et al., 2024) Stretching the shoulder capsule, even allowing for some discomfort, is important to ensure the shoulder joint’s mobility continues to recover. Not having the extreme pain associated with freezing the joint and seeing gradual gains in mobility make this stage tolerable.

Treatment

Frozen shoulder treatment starts with physical therapy and joint stretching. Anti-inflammatory medications, ice and heat application, and alternative therapies can all help manage the discomfort. A healthcare provider may also recommend a corticosteroid injection to reduce inflammation, relieve pain, and expedite improved mobility. Redler L. H. & Dennis E. R. 2019)

Surgery is seldom needed but is an option for treating a frozen shoulder. It is usually only considered if prolonged efforts at therapy have failed to improve symptoms. One of the problems is that surgery could worsen shoulder problems. (Le H. V., Lee S. J., Nazarian A., & Rodriguez E. K. 2017)

Prognosis

The timeline for recovery can be long, measured in months and possibly years. (Le H. V., Lee S. J., Nazarian A., & Rodriguez E. K. 2017) Expecting a quick recovery can cause more frustration. However, individuals can take steps to speed their recovery and reduce discomfort. Physical therapy can be beneficial, and a healthcare provider can suggest treatments to help alleviate pain while recovering. Over time, almost all patients will find complete relief and a normal or near-normal range of motion in their shoulder joints.
