Dystonia, severe, forceful, sustained twisting movement and postures, can be associated with Parkinson’s disease and Dystonic spasms are among the most painful symptoms a Parkinson patient can have. The limbs, trunk, neck, face, tongue, jaw, swallowing muscles and vocal cords can all be affected by PD.
A common form of dystonia in PD involves the feet and toes, which may curl painfully. Dystonia may also cause an arm to pull behind the back, or force the head forward towards the chest.
‘Central pain’ is the most alarming pain syndrome in patients with PD is also one of the rarest. This affliction – which is presumed to be a direct consequence of the disease itself, not the result of dystonia or a musculoskeletal problem – is described by patients as bizarre, unexplained sensations of stabbing, burning and scalding, often in unusual body distributions, such as the abdomen, chest, mouth, etc.
Akathisia, or restlessness, is a frequent and potentially disabling complaint and form of pain. Some patients with this condition are unable to sit still, lie in bed, drive a car, eat at a table or attend social gatherings.As a result of akathisia, patients may lose sleep or become socially isolated. Akathisia is not connected to Restless Leg Syndrome, another common condition associated with PD.
