<bot>: Hello! Thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms seem to be related to a musculoskeletal issue. A backbone disorder can not be excluded as a possible cause of this symptomatology, related to a possible nerve compression (as your symptoms are modulated by the right arm movements). As far as your cardiac and lung tests have resulted normal, there is nothing to worry about. I recommend performing a cervico-thoracic column X-ray study and a nerve conduction study. Anxiety should also be taken into consideration, if all the these tests result normal. Hope to have been of help! Greetings!
