<s>[INST] I am of age 20. But i have blood pressure. Normally my blood pressure is 140/100. I have check up several time and once docter has prescribed me to take medicine too. But i didnt start because after sometime it was normal. Nowadays i am feeling little pinch in my heart sometime and there is so much fluctuale in my pressure. What is its cause and should i start taking medicine. [/INST] HIT hanks for posting your query.  Pinch in the chest region could be due to Acidity or muscle irritation. I don't suspect any heart problem at your age.  Just eat food at right time and avoid spicy and non veg food.  Chat Doctor.  Regarding whether you need to take medicine for blood pressure, I would advise not to take as it is marginally high. Start doing aerobic exercise like Brisk walking, Jogging, running, cycling or swimming for at least 15 minutes a day.  Recheck your Blood pressure after 2 months and if it is still 140/100 or more you need to start the medicine. Hope this was useful to you. Any clarifications feel free to ask. Regards. </s>
