Thanks for your question on Healthcare Magic. I can understand your concern. No, these symptoms are not normal. You should definitely consult doctor immediately. Possibility of heart related diseases is more. Rapid heart rate, low blood pressure, twitching etc are commonly seen with heart diseases. So consult doctor and get done 1. Blood pressure monitoring 2. Ecg 3. 2d echo. If all these are normal then no need to worry for heart diseases. Sometimes, stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relax and calm. Don t worry, you will be alright. But first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
