I'm 16 and the last couple days I've felt like my chest has a sore feeling to it. It's hard to explain but it is very uncomfortable. A couple days ago during pull vault I was about to do my vault and all of the sudden I got a weird pain in my chest that caused me to stop and just take a break. I didn't really pole vault after that because I was so scared it was going to happen again. I've gone to the cardiologist and they said my heart is fine. I have a little hiccup on my ekg maybe indicating an I larger left life of the heart but after they ised an ectocardiogram it showed that my heart was completely normal and they said I had like an athletic heart. That all happened about 2 months ago. I was completely fine for a couple weeks and then my family went on a trip to Florida.(I live in Michigan) and I started to feel like it was hard to breath, always wanted to get deep breaths all the time. But every time I went to play tennis, basketball, or workout I felt completely fine. It only happened when I was relaxing. That really worries me and I thought I would die from asthma or some lung desiese.( I've never had asthma before so I was even more nervous because I didn't have an inhaler) once I got back to Michigan I started to feel better but then just a couple days ago I'm started to feel like I'm sick again or going to die. Really worried and want help. Some symptoms I've experienced are chest discomfort, light headedness, and just scared all the time. On Tuesday I worked out for about 6-7 hours with a combination of track, lifting, and basketball, hoping that all the aching in feeling right know is from that. I know that god is watching over all of us but I really would benefit from some tips on what to do.
