Hi, welcome to HCM.
Pain in your both arm is not related to heart. It is most probably a radiculopathy
due to cervical disc herniation.
I will suggest please consult a board certified orthopaedician and get yourself examinee.
Also ask for MRI
of cervical spine
. You need regular exercise for strengthening cervical muscles. Your cardiac work up is already normal.
Hope I have answered your query.
