Hello!
Welcome and thank you for asking on HCM!
I understand your concern and would explain that your symptoms don't seem to be related to any cardiac disorder.
Your performed cardiac tests indicate an optimal function of your heart. A normal echo-cardiogram result would confirm this fact.
This means that other tests need to be done, to find the real cause of your symptomatology (an extra cardiac cause).
A cervico-thoracic
spine disorder (like degenerative changes, and a disk diplacement) could cause
chest pain and
radicular pain in your left arm.
A cervico-thoracic spine x ray study and a
nerve conduction study are needed to rule in/out the above mentioned disorder.
Besides, a gastro-esophageal disorder (like reflux, hiatal
hernia) could also cause similar symptoms. Do you have heart burn or burping?
A fibrogastroscopy should be done to exclude this possible disorder.
Hope to have been of help!
Best regards,
Dr. Iliri
