need diagnosis neck pain

I am a 40 year old female.  I have had my share of car accidents in the past, but nothing recent.  One day I was in a hurry and threw my head back quickly when I was gargling.  It felt like something snapped.  Since that day, I have had nothing but problems.  According to my MRI's and X-rays, I have the following problems:

Straightening of the cervical and lumbar spine, two bulging discs at, I think, C5 and C6, extra bone growth on two cervical  vertebrae, two vertebrae that have shifted (one forward, one back) at the same site as the bulges, narrowing of the facet joints or foramen (wherever the nerves thread through).  I have chronic muscle spasms and pain in my neck and shoulders.  Most of the pain is on the left side.  X-rays from the front view show my head tilted sideways a little when I was trying my hardest to hold it perfectly straight.  I have been to three different physical therapists with a variety of treatments, and just started seeing a chiropractor. I have done Korean Yoga and accupuncture, as well as home traction with an over the door water bag.  I have been seeing a pain management doctor for almost three years now.  I have had 4 epidural injections around the facet joints and radiofrequency in many locations in the cervical spine, along with  many trigger point injections in my shoulders.  I tried to get them in my neck but it made it worse..  My cervical range of mobility is very small.  My shoulders look like I am holding them up all the time (and they feel that way too) The are constantly sore and full of knots. My neck is constantly stiff and it hurts just to hold my head up. I am a teacher and need to constantly look down to read, grade papers, etc. which makes it even worse. I try to sit in a way that I can put books, and papers higher up in front of me.  I use heat a lot and have tried ice but it gets worse.  The chiropractor said I have the spine of a 55 year old.  My report said I have degenerative disc disease and I don't remember what else.  My most recent "diagnosis" from the Chiropractor is this:  He said I need to get the curve back in my neck by laying on a rolled up towel and that my neck muscles and ligaments  in the back are too stretched out and the muscles and ligaments in the front are too short.  He said if I hang my head upside down off the edge of my bed or roll back on an excercise ball and stay there for 20 min. each day, that my discs will go back to where they belong and my pain should go away.  He sounds like he doesn't really know what he is talking about but of course I can't be sure.  I have been told by two therapists that my ribs are out of place.  One guy said that one of my legs is much shorter than the other.  I have been on Vicodin and Soma for almost 3 years and have to take Protonix for excessive stomach acid.  I have also been on antidepressants since I was 26. I have had low back pain since I was a teenager.  Sometimes I can't step down without a sharp pain in my lower back.  I get hip pain sometimes as well.  

My mother started having problems in her late twenties which began with a ruptured disc and spondylolithesis. She had laminectomies and several failed fusions.  In one surgery the inserted Harrington rods to help the fusion stick.  It broke anyway and the rods were too tight.  Now she is permanantly bent over and has spinal stenosis and arthritis.  She never saw a chiropractor or physical therapist.   My Uncle has spinal problems as well.  Supposedly, his spine is too small for his body and he recently underwent surgery at Barrows Neurological Institute.


Here is my question:  What is wrong with me and what can be done about it?  I am looking for something more permanent than all these temporary fixes that hardly work and only last 1-3 days if that. My quality of life is in the toilet.  I can't lift or bend without paying a steep price the next day. I am always irritable and just want to be left alone.  Please help.
