I recently had a heart attack. The symptoms were easy to attribute to “other” illnesses: i.e stomach issues; flu: etc. I ignored my pain for four days. By the time I went to the ER, I had allowed the heart attack to cause permanent, extensive damage. I was forced to wait two months for my heart to heal before open-heart surgery to replace valve and two by-passes.
Please ladies: heart attack pain can feel like muscle strain (through the shoulders) – pain into the jaw as well as nausea and other symptoms.
