Since fall in 2017, I've been having heart palpitations and a little bit of chest pain, but it wasn't bad and only occurred once in awhile. I had an EKG and 48 holter monitor done, but no symptoms occurred then. But since January, it's been getting a lot worse. I have chest pain and palpitations every day. The pain is sometimes sharp, sometimes it's achy and throbbing, and sometimes it feels really tight, especially when I lay on my side. I've been taking my heart rate daily, and sometimes it goes over 100 when I'm just sitting. I took my heart rate after waking up once, and it was at 128. Sometimes I have episodes where I'll being doing nothing and my heart will start pounding and hurting really bad, but it goes away after a minute or two. I haven't had any shortness of breath or any problems breathing, but back in October I fell and hit my calf pretty hard, to the point where it now looks like my leg is dented. My doctor said there was a blood clot but that it would go away on its own, but even now it's still bruised. I don't know if that has anything to do with it, since I've had heart symptoms before I hit my leg, but it's slowly gotten worse after I did. I've also been coughing and getting hot flashes too, but I don't know if that's related either. I'm a 14 year old girl, 5'2, 90 lbs, with no other health problems
