Without the ability to examine you and obtain a history, I can not tell you what your symptoms are from. However, I will try to provide you with some possibilities
Spinal myoclonus can be of many causes, including structural lesions in the spine, in some cases peripheral nerves (if the myoclonus is segemental) or due to some rare neurometabolic disorders. In general, in studies of spinal myoclonus, symptoms have not progressed but rather remained stable or improved.
A progressive myoclonus would suggest progression of the underlying disorder leading to it, such as an ongoing metabolic disturbance. However, in studies of patients with spinal myclonus for which a cause could not be identified, particularly when it is getting worse, stress has sometimes been found to be either a cause or a contributing factor, and addressing underlying stress and anxiety, best with the aid of a psychologist, is important.
Thank you for using the forum I hope you find this information useful good luck.”
