I think you'd better stay with the job until you can find out what's wrong with your back. DO NOT GO TO A CHIROPRACTOR! That's the most dangerous thing a "spinal patient" can do when they don't know what's wrong with their back!! My Neurosurgeon told me that a spinal patient can end up paralyzed and in a wheelchair by going to a chiropractor because just one adjustment can cause permanent damage!! So do NOT go to a chiro!!!

Get the tests done that you need. I've been a spinal patient for 27-28 years and have had every test available done. I think you need an MRI with and without contrast material done. That way they can see what's going on with the discs and soft tissue as well as the bones. An X-ray will NOT show the discs. The discs are soft tissue and X-rays only show bone. So wait til you can get your tests done under insurance before you make any decisions to quit. You need that insurance!!! Actually you need that job! After the tests, perhaps they can put you on light duty, depending on the results.

Best of luck. Let us know how it comes out, ok? Hugs, Lee
