Hi, I've alway suffered from becoming nauseous after running or working out too hard. I used to think it was dehydration but now think it has something to do with my heart and sporadic arythmia.
Tonight, I became severely nauseous after a short, high-intensity workout at home. I didn't vomit but had to stay on the ground for about 25 minutes. I saw flickering white and colored static, had ringing in my ears, sweating, dizziness. I couldn't move and had to lie on the floor half-conscious till the feeling subsided.
Do I have a weak heart? Am I just prone to over-exerting myself?
