Hello, I'm christian mitchell, 15 years old. Ms couple months ago I had some palpitations. They worried me and I saw a cardiologist, had and EKG and wore a 48 hour heart monitor. Everything came back fine. I forgot about it really. Then maybe 3 weeks ago I had a sharp pain in my chest. I thought I was having a heart attack and it really freaked me out. I worried about it for a little bit but then it went away. Just recently the pain has come back and I've been to 4 doctors. I know about costochronditis and that is what I have. Sharp pain on the left side that Radiates to your back. I've stopped worrying about my heart, but I'll go back to that. I have a sinus infection and I've been feeling really weird, not dizziness but foggy feeling. A little imbalanced and alittle confused. And while all of this has been going on I've had about 4 anxiety attacks so not so bad but my anxiety , stress and depression levels have gone up. I feel worried about the dizziness/fogginess, my eyes also feel slow and I'll look at something and it'll still be there faintly when I look away. This could be normal symptoms of a sinus infection. I could just be worried about my body and be blowing all of these symptoms. All of this has happened and I started to check my heart rate, which I realize is the dumbest shit to do if you have previous anxiety about your heart. I feel like it's beating too low. I measured and it was roughly 61 beats per minute I realize that's not low but doctors projections or the 60-100 or 50-70 heart rate ranges for being okay. I just feels slow. Again the dizziness and foggy feeling, eyes feel slow is most likely caused by sinus infection. But I worry about my heart not pumping fast enough. It's funny because the doctors would never know about this because I have white coat syndrome and my heart rate/blood pressure shoots up as soon as I have that band put around my arm and I feel everything relax and heart go down as soon as the doctor takes it off. I'm seeing a therapist today and I'm feeling alittle better. I've been missing school days because I also have a fear of fainting (with my parents okay). Has anyone ever been through this or anyone who has any ideas about it?? Thanks.
