What could cause heart palpitations, dizziness, and breathing difficulties?
What could be the cause of these symptoms? These all happened suddenly… heart racing/palpitations (lasted less than a minute), feeling dizzy/light-headed, slight difficulty breathing… Lately I have also been having random pains down my right arm, and up near my right collarbone… I also realize these might be completely unrelated to the other symptoms… I’m 20 years old, and I do realize that if symptoms continue or get worse, I should see a doctor, but if you could direct me to a medical site that could help, it would be great!
