<s>[INST] I feel cold inside my chest. I just worked out. I ve had a sinus headache all day. I was sweating considerably more than usual during my workout and my heart rate was higher than usual. No palpitations, no dizziness, no blurred vision. My blood pressure was slightly increased yesterday, 160/82, possibly due to stress. But was 132/78 just a few days prior. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. In my opinion you should consult doctor and get done ECG and 2d echo to rule out heart diseases. You are having high heart rate, high blood pressure occasionally, headache and chest discomfort. All these are commonly seen in heart diseases. So better to first rule out cardiac diseases. And hence ECG and 2d echo are required. If both these are normal than no need to worry about cardiac diseases. Your symptoms are mostly due to stress and anxiety. So better to avoid stress and tension. Be relax and calm. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks. </s>
