Can arthritis cause numbness?
Numbness is often a symptom of nerve involvement. For instance, numbness in the arm may be related to nerve irritation in the neck. In such a situation, turning or bending the head to the involved side may increase the symptoms. For example, a pinched nerve in the right side of the neck may cause numbness in the arm and hand when a person attempts to look back over the right shoulder. If nerve irritation becomes more severe, the arm and hand may become weak. A physical examination X-rays and an MRI of the neck and electrodiagnostic tests may be useful in establishing the diagnosis.
