Short answer: Yes, please go to the emergency department to rule out angina, or impending
heart attack.
Long answer:
Hi there,
I would be more cautious because I am assuming that you are taking the Metoprolol and
Simvastatin for
high blood pressure and
high cholesterol. This means that you are at higher risk than the average population for getting heart attacks, on top of the increased risks of your gender and age.
Yes, heart attacks can be felt as just a discomfort, and yes, can be felt at the back as well. The other thing that can feel that way is
acid reflux, but it is less common to have arm tingling with reflux. Plus, it is far less dangerous to have reflux than a heart attack, so I would rule out the life threatening possibility first.
The other factor is that you have already been having it on and off for a week, which may be a sign that your coronary arteries are getting more blocked with time. So I would highly suggest that you get yourself to the emergency room as soon as possible.
Hope this helps, and keep well.
Regards,
Dr. Teh
