My 18 year old son is experiencing a tingling sensation in his heart area. He feels no pain but is concerned with the frequency and intensity of these tingling sensations. He recently competed in athletic activities and felt fatigued after playing just a short time. I took him to the doctor and they seem to think we should consult a cardiologist but their office doesn't have any appointments until three weeks from now. What do you think we should do? Does this tingling sensation warrant a visit to the emergency ward? Please advise!! Frustrated mom
