I was diagnosed with a Heart Arrhythmia at a very young age. I have always been pron to fainting easily, If i ride Roller coasters I pass out on the first drop every time and come to when the ride is stopped and over' this first happened when i was 10 and the first time ridding them. I usually carry 81mg aspirin with me do to chest pain and tightness. But I need feedback on how much to take' cause I also have extremely Low Blood Pressure. What I need to know is if taking a Blood Thinner Like Aspirin' will it cause more harm than good. I also have very low sodium. So with super low blood pressure and with Sodium Levels Barely detectable Doesn't that mean my Blood is already to Thin? So should i not take Aspirin and if so than why does it get rid of my chest pains?
