My jaw has been dislocated for four days?

So, i've had problems with my jaw for a while now (six months?) and it sometimes Pops out, i just move it and it goes back in but it hurts like hell. Anyway, sometimes in the morning its out and I pop it back in. But woke up few days ago and I couldn't get it back in. I've tried everything (expect the doctor/dentist cause I'm broke) and its been four days still hurts like heck and i can't open my mouth very far, can hardly eat/bite. I'm going to try and get a doctor to look at it tomorrow but my question is: Does it matter if it's out for this long? Wll it make it worse?
