Yep, sounds like the start of hot flushes to me. Usually begins with a feeling in the stomach and also a feeling of dread/foreboding/not feeling quite right. This can vary in intensity and is then followed by feeling very hot. Once you cool down, its over until the next time. So, no, not just feeling a bit hot, more like a whole body experience. Have had a lot of experience having had them for over 12 years! As someone once said, 'the menopause is a gift that just keeps on giving'!
