<s>[INST] Hi I had a piercing pain in the left side of my chest. Like a needle piercing my heart. I went all light headed and needed to sit down. I then experienced a hot flush where i actually had sweat beads on my forehead. I have had an ECG, all clear plus a heart scan and that was clear [/INST] Thanks for your question on Healthcare Magic. I can understand your concern. No need to worry for heart diseases because your ecg and heart scan reports are normal. Sometimes, stress and anxiety can also cause similar kind of symptoms. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on it's solution. You may need anxiolytic drugs too. Don't worry, you will be alright. Avoid stress and tension, be relax and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
