Dystonia is another secondary motor symptom of Parkinson’s that you may experience. When you have this condition, you’ll feel your muscles make repetitive and involuntary movements. This will cause your body to twist in certain postures, preventing you from doing movements you want. 

Furthermore, it may affect your limbs, torso, neck, and even your eyes. Dystonia is painful at times, but not always. But keep in mind that it can also mean that you have a genetic disorder or brain lesions. Sometimes, it’s also a side effect of the medicines you’re taking.
