Absolutely 100% this. When I had my heart attack I'd no idea what it was. My main thought was I'd bonked. After getting home I told myself look Paul, you're 61, something doesn't feel right, get to hospital. I now know, because I experienced them for 3-4 months during rehab, the little twinges I had for years were in fact my heart. Get it checked out! Apparently it's more difficult to detect early signs of heart attack in women so ladies should be even more aware. There's no need to feel embarrassment. Couple of years ago I found a pea sized lump in my groin. Phoned the surgery at 8.00am and was offered an appointment three days hence. I said to the receptionist I'm 60, I have lump in my groin. Oh, can you get here by 10.15! When my GP pronounced it was a.cyst I first laughed with relief and second felt very embarrassed. She was quite clear, any symptoms of major issues see the GP immediately.
