Suggest Remedy For Pain In Chest

I was wrestling last night and my boyfriend accidentally like put his head in my chest and pushed. He wasn't trying to hurt me but after he did that i had really shortness of breath and a lot of pressure on my chest it. After I got up i had a really hard time moving and very sharp pains in my chest. It doesn't hurt as bad if i stay in one position while laying down or sitting, but when i start to move or try to pull myself up I have extreme amount of pain. Last night it hurt to laugh. I am worried it could be worse than just a bruised sternum, but i don't want to go to the doctor for a couple days just in case it goes away. what is your opinion?
