A 48-year-old male patient presented with complaints of difficulty holding a pen, inability to write more than four sentences, and cramping of the fingers. The patient noticed that these symptoms started 6 months ago but neglected them as he thought it might be due to stress. However, the pain and cramps in his fingers and hand worsened over time. The patient is a non-smoker and consumes alcohol occasionally. There is no family history of paralysis, seizures, or chronic illness. On physical examination, thumb extension and hyperextension of the finger were noted when the patient was asked to write. His blood pressure was 145/90 mmHg. The laboratory investigations were normal.
