I dont know what to do.

A few days ago, I started to get heart pain, I told my mother about it and how I said I wanted to go to a doctor. She said it was Jesus knocking on my heart. I asked my dad later and he said he thinks im fine. Now I am having some symptoms of cardiovascular disease like arm pain and jaw pain (granted it comes at random moments and its possible they are totally seperate events) but I am still scared about it and I cant do anything about it.

What can I do to convince my parents to let me check it out?

Try guilting them into it, look up relevant interwebz pages and let them point it out to them. It is probably nothing, but the worry wont go until you see some one.
