I wake up during the night with bilateral arm pain/numbness, not being able to move them.  At the same time there is pain radiating from my chest through to the back between the shoulder blades.  Is this a heart attack?  I am 61 year old female with hyptertension and borderline cholesterol.
Though atypical chest pain during a heart attack may be as what you have described, However the kind of pain and numbness particularly inability to move them points towards more like pain of cervical spondylitis.  The pain radiating from chest to in between shoulder blades is more characteristics of aortic root dissection or reflux gastritis. Because of the risk factors just a basic EKG if the pain is persistent and increase on exertion and there is associated breathlessness, palpitation, sweating, to rule out cardiac event.
