<s>[INST] My heart will start to beat really fast and it will feel like when i breath it is inhaled through a filter. at times i fell hot, but not really if that makes sense at all. sometimes i get pain that isn t a constant. sometimes its just in the chest. sometimes its through the neck also. sometimes the pain is feeling like sinus pain as well. and sometimes my whole body. i can move freely and rarely get to the point where i feel like shouldn t move. In a sense to me it sounds like a heart attack, but i have had this problem randomly (maybe 3-5 times a year) its a god aweful feeling. i can remember first experiencing this when i was about 8 or 10 (earliest memory of it) just walking outside. other times its after a bike ride, running, or just doing daily things. its not always an active attack, it does happen when im not doing anything at all too. [/INST] Helloplease be assured that these are all your subjective feelings. Heart attacks are acute conditions where you get chest pain or back pain or hand pain. With each heart attack, some part of the heart muscle dies. So the heart pumping function also decreases. I don't think that's the case in you. Believe me having 3-5 heart attacks a year is quite unlikely in your case. These are just some vague pains arising out of hyperacidity which you then stress on, which in turn increase your subjective feelings. Take a course of antacids pantoprazole 40 mg twice a day before food for 7 days and then once a day for 14 days. Thank you </s>
