Parsonage-Turner Syndrome, also known as acute brachial neuritis, is a rare neurological disorder that affects the nerves in the shoulder and upper arm. It is characterized by sudden and severe pain, followed by weakness and muscle wasting in the affected area. The exact cause of Parsonage-Turner Syndrome is unknown, but it is believed to be an autoimmune response triggered by an infection or injury.
The symptoms of Parsonage-Turner Syndrome typically begin with intense shoulder pain that can radiate down the arm. This pain is often described as burning or stabbing and can be debilitating. After the initial pain subsides, weakness and muscle atrophy may develop, leading to difficulty with everyday tasks such as lifting objects or raising the arm.
Diagnosis of Parsonage-Turner Syndrome is based on clinical symptoms, physical examination, and ruling out other possible causes of shoulder pain. Treatment focuses on managing pain and restoring function through physical therapy and pain medications. In some cases, surgery may be necessary to repair damaged nerves or tendons.
While the prognosis for Parsonage-Turner Syndrome varies, most individuals experience gradual improvement over time. However, recovery can be slow and may take several months to years. Rehabilitation and support from healthcare professionals are crucial in helping individuals regain strength and function in the affected arm.
