<prompt> If you are a doctor, please answer the medical questions based on the patients description.ive been getting random jolts in the left side of my neckear and also in my chest around my heart. This has been going on for over a year and happens about 5 times a month. It jerks my whole head and I seem to llose control of my head very briefly.What could this be?  <response>: Hello! Thank you for asking on Chat Doctor! Your symptoms could be related to myoclonus. For this reason, I would recommend consulting with a neurologist and performing an EEG. Other tests to consider would be: complete blood count for anemia, thyroid hormone levels for thyroid dysfunction, blood electrolytes for electrolyte imbalance, calcium plasma levels and vitamin D plasma levels for possible deficiency. In the meantime, I would recommend treatment with clonazepam. You should discuss with your doctor on the above issues. Hope to have been helpful! Best wishes,
