question: Im 16, and I frequently have chest pain. It usually feels like my chest is being squeezed really really tightly and sometimes like somethings stabbing it. If Im standing up, I usually get dizzy when my chest starts hurting. I also occasionally just get dizzy. I have headaches really frequently as well. The chest pains are really random. If I exercise or climb up stairs, they start and dont stop til I rest, but they also just randomly occur. Heart attacks are rare in teenagers,but what could it be?
