Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms could be related to anxiety. Anyway, considering the procedure that you have gone through, I would recommend performing further tests to exclude other possible causes that may mimic this clinical scenario: - complete blood count for anemia - thyroid hormone levels for thyroid gland dysfunction - blood electrolytes for possible imbalance - a cervical spine X ray study for possible degenerations in this region or a bulging disc which may lead to irradiating numbness in the arms - inflammation tests (PCR, ESR) to investigate for inflammation. You should discuss with your doctor on the above tests. Hope to have been helpful! Wishing good health, Dr. Iliri
