Shoulder Pain  

Shoulder Joint Anatomy
This particular joint is intricate and complex area of the body. While the shoulder is one of the most amazingly versatile parts of the body, it is also among the most fragile. With the number of tendons, bones and muscles involved with each movement, it's easy for something to go wrong. The shoulder joint also has a large range of motion, but that means that it lacks the stability that other joints have. This makes it more susceptible to injury resulting in shoulder pain.

Three Bones in the Shoulder

• Scapula (shoulder blade)
• Humerus (upper arm bone)
• Clavicle (collarbone)

Four Muscles in the Shoulder

• Supraspinatus
• Infraspinatus
• Teres Minor
• Subscapularis

When we talk about frozen shoulder, we are talking about the point at which the humerus fits into the shoulder socket. The surrounding ligaments and capsule becomes inflamed and causes limited motion in the area and a great deal of shoulder pain.

Causes of Frozen Shoulder
Although the cause of frozen shoulder is a mystery, many cases of this condition occur following a shoulder injury, shoulder surgery or arthritis. Poor posture is also a cause of frozen shoulder, causing the ligaments that surround the shoulder joint to shorten and cause stiffness in the joint. Others believe that conditions like diabetes and hyperthyroidism can cause or at least contribute to stiffness in the shoulder.

Symptoms of Frozen Shoulder
You might not know what causes frozen shoulder, but you definitely know when you have it because of the extreme stiffness and shoulder pain you'll feel in the joint. The pain is usually more like a constant aching and the stiffness prevents the joint from performing its full range of motion. In a typical case, you won't be able to lift your arm above your head or rotate your shoulder at all. There are generally three stages involved with the condition:

Stage One
This is known as the "freezing phase." The shoulder begins to have mild pain and stiffness. It can last for a few weeks or several months.

Stage Two
Known as the "frozen phase," this stage sees the pain decline while the stiffness remains. This stage can last up to a year.

Stage Three
This "thawing phase" allows the shoulder joint to regain its full range of motion, but it could take up to a few months to fully recover.

Most cases of frozen shoulder clear up between four to six months after onset, but some extreme cases have been known to last a few years. Proper precautions and exercises can reduce your risk of getting this condition and any other type of shoulder pain.
