                        Go to a doctor and arrange for X-rays or an MRI - you CAN set up a payment plan.  You might have a herniated disc or something which could be very serious!  I think there is a thing called the Hill Burton Act which says that a (participating) hospital HAS to treat you if you can't pay.  Maybe call a few hospitals?
