I'm now 64 years, history of high blood pressure. Last August had a heart attack and a stroke; also it was discovered I had a clot in a venticle of my heart. NO PAIN whatsoever, just flu like symptoms, vomiting and diaherrea ! Had gone to a dr on a Mon and she said I had a "bug" treated the symptoms and sent me home.On Sat. I was found unconscious and rushed to ER; heart attack and stroke. Was transferred to a major ATL hospital for a heart cath; arteries were absolutely clear, no cholesterol at all. Mother died at 51 with congestive heart failure and 10 days later her 54 yr old brother died to massive heart attack ! So,I'm predisposed to heart issues; they were smokers and I've never been. All to say that you never know what your symptoms might be; go to ER !
