If a patient is experiencing dyskinesia, it means that they are having painful movement.

No, that is not accurate. Dyskinesia refers to an abnormal and involuntary movement disorder that can involve various body parts. It is not specifically related to pain. Dyskinesia can sometimes be a side effect of certain medications, such as those used to treat Parkinson's disease. The movements associated with dyskinesia can be jerky, twitchy, or writhing in nature, but they are not necessarily painful.
