Welcome to HCM
We understand your concerns
Your description is good and up to the point. In the case of clear EKG and clear chit from doctors, you need not to worry. But you should worry about the neck and shoulder pain
because it is possibly due to anxiety
about your health. This is called hypochondriasis
. Ignore the pain and change priorities. Consult a psychologist
for help. I can help you online if you desire so.
