Dyskinesia is involuntary, irregular movement that can occur as a complication of long-term levodopa use combined with a longer course of Parkinson's disease (PD). It doesn't happen in everyone, and it occurs to different degrees. In some people, it may be painful or bothersome. Others actually prefer the extra movement of dyskinesia to being rigid or otherwise unable to move because of PD. (Dyskinesia is typically present when other Parkinson's symptoms, such as tremor and stiffness, are under good control.) If dyskinesia occurs, medication adjustments may help.
