Frozen Shoulder Pain and Adhesive Capsulitis
Treatment and prevention tips for frozen shoulder pain.

Side note: Frozen shoulder is different from rotator cuff injury, tear, or strain. Frozen shoulder affects the joint capsule, whereas rotator cuff injury affects the muscles and tendons of the shoulder joint.
Anatomy of the Shoulder Joint
The shoulder joint is a truly remarkable creation. It’s quite a complex formation of bones, muscles and tendons and provides a great range of motion, including flexion, extension, adduction, abduction, and internal and external rotation. The only downside to this extensive range of motion is a lack of stability, which can make the shoulder joint vulnerable to injury.
The shoulder is made up of three bones, and the tendons of four muscles. (Remember, tendons attach muscle to bone). The bones are called the “Scapula,” the “Humerus” and the “Clavicle.” Or, in layman’s terms, the shoulder blade, the upper arm bone and the collarbone, respectively.
The four muscles that make up the rotator cuff are called, the “Supraspinatus,” the “Infraspinatus,” the “Teres Minor” and the “Subscapularis.” It is the tendons of these muscles, which connect to the bones, that help to move your arm.
Frozen shoulder occurs in the shoulder joint at the point where the humerus bone fits into the socket of the shoulder, (the glenohumeral joint). The supporting ligaments and surrounding capsule become inflamed causing shoulder pain, stiffness, and limited motion.
Causes of Frozen Shoulder
The exact cause of frozen shoulder is unknown, however in several cases, frozen shoulder occurs after another shoulder injury like rotator cuff tear, arthritis, or shoulder surgery.
Also, poor posture can cause a shortening of the ligaments around the shoulder joint, which can lead to frozen shoulder. Other theories have suggested that hormonal and genetic conditions like diabetes and hyperthyroidism can also contribute to frozen shoulder.
Symptoms of Frozen Shoulder
The most common symptoms of frozen shoulder are pain and stiffness. Pain usually takes the form of a persistent dull ache and stiffness prevents the full range of motion of the shoulder and upper arm. Patients are often unable to lift the arm above their head or rotate their arm inward.
The normal progression of frozen shoulder has been described as having three stages.
- In stage one, (the freezing phase) the patient begins to develop mild pain and stiffness in the shoulder joint. This stage can last from a few weeks to a few months.
- In stage two, (the frozen phase) the stiffness remains but the pain begins to decline. This stage can last from a few months to nearly a year.
- In stage three, (the thawing phase) the full range of movement begins to return to the shoulder joint. This stage can also last a few months.
Most sufferers of frozen shoulder will be fully recovered within 4 to 6 months, but some cases have lasted for up to three years, although these are extremely rare.
Frozen Shoulder Prevention
Mark my words, “Prevention is much better than Cure.” Anything you can do to prevent frozen shoulder from occurring is worth it. The prevention of frozen shoulder and other shoulder injuries comes down the conditioning of the shoulder muscles, tendons, and ligaments, which ultimately involves improving both the strength and flexibility (range of motion) of the shoulder joint.
Also, don’t forget common injury prevention techniques like, warming up properly and using a bit of old-fashioned common-sense. However, for the most part, stretching and strengthening are going to be your best defense against frozen shoulder. Even if you don’t have a shoulder problem now, the following recommendations could save you from a major injury in the future.
- A thorough and correct warm-up will help to prepare the muscles and tendons for any activity to come. Without a proper warm-up the muscles and tendons will be tight and stiff, which may limit blood flow and result in a lack of oxygen and nutrients for those muscles. Before any activity be sure to thoroughly warm-up all the muscles and tendons that will be used during your sport or activity.
- Strengthening and conditioning the muscles of the upper back, chest and shoulders will also help to prevent frozen shoulder. There are a number of specific strengthening exercises you can do for these muscles, including dumbbell exercises and Thera-Band exercises. For a comprehensive, step-by-step treatment program, review my 7 Step Rotator Cuff Treatment and Stretching System.
- Flexible muscles are extremely important in the prevention of frozen shoulder. When muscles and tendons are flexible and supple, they can move freely without restriction. On the other hand, if your muscles and tendons are tight and stiff, it is quite easy for those muscles and tendons to be pushed beyond their natural range of movement. To keep your muscles and tendons flexible and supple, it is important to perform regular shoulder stretches.
Frozen Shoulder Treatment
Frozen shoulder treatment primarily consists of pain relief and physical therapy techniques. Pain relief usually takes the form of anti-inflammatory medication and the aim here is to reduce the pain enough so that physical therapy can be initiated.
Two other forms of therapy should also be considered: heat and massage.
- Heat is extremely good for increasing blood flow to the shoulder. Heat lamps and hot water bottles are the most effective way to increase blood flow, while heat-based creams are distant second choices.
- Massage is also a great way to increase blood flow to an injured area, and of course the oxygen and nutrients that go with it. The other benefit of massage is that it helps to reduce the amount of scar tissue which is associated with all muscle, tendon, and joint injuries.
During this period of pain relief treatments physical therapy should also be initiated. This is an extremely important part of the treatment process and full recovery will not occur without a dedicated approach to physical therapy treatments.
Firstly, don’t stop moving. Some doctors will often tell patients to keep the injured area still, and this is not always the best advice. Gentle movement will help to keep the blood flowing to the injured area. Of course, if pain is present, limit the amount of moving you do, but don’t stop moving all together.
Next, specific stretching and strengthening exercises should be started to help loosen up the shoulder joint and speed up the recovery process.
