A Closer Look at the Different Stages of Frozen Shoulder

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.

Managing Myofascial Pain Syndrome: Breaking the Spasm Cycle

For individuals who have to be in one position for long periods, have poor postural alignment, and perform repetitive motions, what are myofascial pain syndrome spasm cycles?

Myofascial Pain Syndrome Spasm Cycles

Myofascial pain syndrome is a common condition that causes pain symptoms in a particular body area (Jafri M. S. 2014). A myofascial pain syndrome spasm cycle is a recurring pattern in which muscle tension and spasms in affected regions, caused by myofascial pain syndrome, lead to pain, triggering more muscle spasms. This creates a vicious cycle of discomfort and tightness that can be difficult to break without treatment; the pain perpetuates muscle spasms and vice versa.

Spasm Pain Cycle

Left untreated, myofascial pain is often experienced as a recurring cycle of spasm, pain, and spasm. (Kojidi M. M. et al., O2016) The exact cause of the spasm is not known. It may be related to excessive accumulation and release of acetylcholine, which causes sustained muscle contraction. (Nicol A, Crooks M, Hsu E, Ferrante M. 2018) Another theory is that repetitive small muscle trauma helps create a trigger point or knot in the muscle. (Thorne. 2021)

Active trigger points in muscles characterize myofascial pain syndrome. (Shah J. P. et al., 2015) These trigger points cause pain in the area where they are located and sometimes in other places, known as referred pain. Each muscle has a particular referral pattern of pain that goes from a trigger point in that muscle to another place in the body. (Shah J. P. et al., 2015) Medical providers and massage therapists trained in this area can identify trigger points by their pain patterns. With myofascial pain syndrome, muscles tense, and joint range of motion may decrease. (Jafri M. S. 2014)

Trigger Points

  • Myofascial pain syndrome is characterized by trigger points and sensitive knots within muscles that can cause referred pain when pressed, contributing to the spasm cycle.

Muscle Tension

  • A repeatedly tense or injured muscle can develop trigger points, which can lead tocle tightness and potential spasms.

Pain-Spasm-Pain Cycle

  • The pain from a trigger point can cause the muscle to further contract and spasm, leading to even more pain and perpetuating the cycle.

How Spasms and Pain Present

Myofascial pain is often caused by long periods of poor postural alignment, muscle injury, and repetitive motions. (Cleveland Clinic, 2023) For example, the upper body slumps forward when sitting at a desk workstation all day. The upper section of the trapezius muscle is located on the back of the neck and top of the shoulder. The upper trapezius muscle works to raise the head. (Yoo W. G. 2015) The trapezius muscle now has to work more than it is used to. This overuse may cause microscopic muscle injury, leading to muscle spasms and pain. (Bron C., & Dommerholt J. D. 2012) (Nicol A, Crooks M, Hsu E, Ferrante M. 2018) Without treatment, the muscle spasms, pain, and microscopic muscle injury may persist or worsen, leading to trigger points and chronic pain. (Jafri M. S. 2014)

Causes

Repetitive Motions

  • Repeating the same movement, like typing on a computer, can trigger muscle tension and points.

Poor Posture

  • Maintaining incorrect posture for extended periods can strain muscles and contribute to trigger point development.

Muscle Injury

  • Past injuries can leave muscles susceptible to developing trigger points and pain cycles.

Stress

  • Psychological stress can lead to muscle tension and exacerbate existing trigger points.

Break the Cycle

Physical Therapy

  • A physical therapist can use stretching, massage, and trigger point therapy to release muscle tension and address trigger points.

Exercise

  • Regular exercise, including gentle stretching, can help improve muscle flexibility and reduce tension.

Heat Therapy

  • Applying heat to affected areas can help relax muscles and alleviate pain.

Ergonomics

  • Modifying work habits and posture to reduce strain on muscles.

Stress Management

  • Techniques like deep breathing and meditation can help reduce stress-related muscle tension.
