What are the most common causes of numbness in the shoulder?

Some of the most common causes of shoulder numbness are medical conditions such as neuropathy or diabetic neuropathy. A condition known as thoracic outlet syndrome can also cause numbness in this area, along with other symptoms such as tingling in the fingers. Rotator cuff injuries, as well as pinched nerves, are other common causes of numbness, as is multiple sclerosis. Poor circulation in the shoulder area can also cause numbness.

When an individual suffers from shoulder numbness, they may associate this with overexertion or repetitive motion injury. This is often a possibility, although other symptoms may accompany this type of injury, such as swelling and pain. A common cause of shoulder pain, tingling, or numbness is shoulder tendinitis. Often this is caused by repetitive motion stress.

Shoulder tendinitis occurs when the tendons become stretched and inflamed, usually due to overuse. Many people employed in occupations that require repeated lifting or extending of the arm suffer from shoulder tendonitis. Symptoms include pain, swelling, tenderness, tingling, and numbness in the area. Doctors may recommend rest, ice, and shoulder exercises as part of a therapy program to treat this condition.

A rotator cuff tear is another common cause of shoulder numbness. The rotator cuff is located in the upper arm region, or directly on top of the shoulder. It is made up of various muscles and tendons, which are attached to the bone. The rotator cuff can tear due to a repetitive motion injury or an acute shoulder injury.

Severe pain and immobility are usually the most common symptoms of this type of injury, although numbness often also occurs. If the rotator cuff tear is significant enough, it may require surgery to repair it. Arthroscopic surgery, which is usually done with a device known as an arthroscope, may be an option.

A central nervous system disease known as multiple sclerosis can cause muscle weakness and paresthesia. This can cause partial numbness in the shoulder and other areas of the body. In more severe cases, complete numbness of the shoulders and neck can occur.

For some people with nutritional deficiencies, poor blood circulation can occur. This can lead to numbness that affects various areas of the body, including the extremities and the shoulder area. If left untreated, circulation problems can lead to high blood pressure, heart disease, or diabetes. That is why unexplained shoulder numbness must be diagnosed by a medical professional.
