Question: What are the symptoms of Parsonage Turner syndrome ?
Answer: What are the signs and symptoms of Parsonage Turner syndrome? Parsonage Turner syndrome is usually characterized by the sudden onset of severe pain in the shoulder and upper arm, which is often described as sharp or throbbing. In some cases, the pain may extend to the neck, lower arm and/or hand on the affected side. Rarely, both sides of the body are involved. Affected people typically experience constant pain that may become worse with movement. Intense pain can last from a few hours to several weeks at which point the pain usually begins to subside; however, mild pain may continue for a year or longer. As the pain subsides, it is typically replaced by progressive (worsening over time) weakness of the affected area, ranging from mild weakness to nearly complete paralysis. Affected people may also experience muscle wasting (atrophy); absent or reduced reflexes; and/or loss of sensation. In some cases, nerves and muscles outside of the shoulder and upper arm region may be affected, as well.
