I've been dealing with some serious chest pain for the last five months, and along with that, I've been feeling really weak and fatigued. My stamina has dropped a lot, and I get tired super quickly. On top of that, my heart races really fast. My resting heart rate is usually around 80 to 90, but if I start walking, it shoots up to 120, and just climbing two floors slowly takes it to around 160. Is this something to worry about? I had an ECG done, and it came back normal, so I'm really confused about what's going on. Any insights on this would be really helpful.
