Parsonage Turner syndrome
Type of disease: Rare conditions
Parsonage Turner syndrome is characterized by the sudden onset of shoulder and upper arm pain followed by progressive (worsening over time) weakness and/or atrophy of the affected area. Although the exact cause is unknown, researchers believe that most cases are due to an autoimmune response following exposure to an illness or environmental factor. Suspected triggers include viral and bacterial infections; surgery; vaccinations; injury; childbirth; strenuous exercise; certain medical procedures; and various health conditions. Treatment is symptomatic and may include pain relievers and physical therapy.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
