Now pain is going through my whole body. My mom said she thinks it's stress but I think it's more than that. She doesn't think it's that bad where I will have to go the hospital. What do I need to do?

Go to the Emergency room.

Tried telling her to take me but she refuses to. She thinks I will be okay but I'm in pain. She gave me excedrin and ibuprofen. Neither one helped.

I'm not sure whether there's a particular age in other countries, but are you able to make an appointment with your doctor? It's always best to make sure we know what's going on with our bodies. (And if it IS stress, it'll surely get a bit better just confirming that's what it is)

I'm not sure about a doctors appointment. But if a minor goes into an emergency room, even alone, he will be seen.
