I have started with chest pain a couple days ago. It comes and goes at time. I am only 35. Nothing as far as Ibuprofen or antacids seem to help. How do I know if I should see the doctor or what is recommended. I do suffer from back issues as well could this be pinched nerve?

We can't diagnose you online. Something like this you probably don't want to take a chance with and you should get to a doctor.
