lumbar spine fracture

Dear Back Forum,
My low back has been giving me problems, sharp pain that does not radiate.  The pain is so bad I cannot stand for very long, can't do hardly anything standing up.  The only drug that has numbed it is Lyrica.  I take opiates for bad legs.  My first question is, on a plane black and white X-ray, does a fracture show up as a white line?  On my X-ray, the last lumbar bone has a white cracked line in it, that goes from back to front about halfway across the bone.

Also, I have a question about the relationship of the sacral spine to the lumbar spine.  A lateral X-ray was taken of my low back with my legs bent, the only way I can lay comfortably.  Should the sacral spine be horizontal to the lumbar spine if the knees are bent?  All the disk spaces are where they are supposed to be.

My history and pictures show the thoracic spine with compression fractures from a falling accident many years ago, on X-ray the bones appear crumbled on the edges, with white cracked lines here and there, disks vapororized, the bodies misaligned and teetering on top of each other.  At the time, the pain was sharp, natural fusion took place over time, now the pain is just deep aching muscle pain from being permanently wrenched out of place.  X-rays have always shown the upper spine noticeably curved sideways.  A few weeks ago, when a neurologist looked at a recent X-ray, he was obviously shaken and went, "No, no, no."  So, it's a bad place for sure, even all these years later.

Now, the lower back pain that is the subject of this post, it began several years ago, I thought it was just an aging processs, maybe the disks were fading so the bones were against each other, or arthritis, or something.  Recently the pain became quite sharp, so I had an X-ray, and all the disks are in place.  I was declared normal in the lower back.  But how come the pain?  

So, I look at them X-rays.  What I did notice, in the frontal view of the whole spine, the lower spine leans in the opposite direction of the original thoracic injury's curvature.  The orthopedist did suggest the old injury may be affecting the low back somehow.  Also, in the lateral view, my low back is swayed more than normal pictures I've seen.  Also, the lateral X-ray of my low back, it was taken with my knees bent, since that's the only way I can lay comfortably, and yet it shows the lumbar and sacral bones are perpendicular to each other, a 90-degree angle.  I know the lumosacral spine has an angle, but this was nuts, particularly in view of the fact that my knees were bent...it shouldn't have been as sharp an angle even if my back wasn't hurt.  

That orthopedist who looked at the X-ray, perhaps did not understand why I was there, he did not go over my X-rays, he did not address the sharp back pain until I asked him, that is, if my low back was normal, how come it hurt, and he came up with the answer he suggested above.  Maybe he thought I was seeking drugs.  Hey, I've got plenty of those.  I wanna know why my back ain't workin right, the pain has to be comin from somewheres!  And he goes and says I should do therapy.  My family physician advised me not to, instead upped my antidepressant.  *Sigh*

Anybody who knows what a plane black & white X-ray looks like when the bones are broken, that is, are there white lines that indicate this?  And anybody who knows what an X-ray looks like when there is a misaligned lumbar spine as relates to sacral spine, does mine sound off?

I already have experienced all the problems associated with the break in my thoracic spine, it hopefully will not "go anywhere," I've gotten used to it, never complained the day I got out of the two-month hospital stay to the day I had the low back X-rayed.  But the lower back seems to be affected either by the old injury, or maybe I had a new injury or worsening of a relatively newer injury and I just don't remember.  I feel like I did when I broke my upper back the first time long ago, it hurts the same way and plus I'm afraid it's fixing to fall off itself and injure me.  

One doctor says physical therapy, another says no therapy, another says it's not nerve pain rather it's muscle pain.  I say I've got a broken bone because that's how it feels.  I also think I've got a whole spine that is about to get broke.  See, not only do I fear therapy, but I'm pretty scared if I get twisted somehow or other, the whole lumbar spine is going to fall off the sacral spine, from the way the pictures look.

Sorry I can't edit this.  I have some mental deficits.  Anybody that can shed light on this in any way whatsoever, I would appreciate some opinions.  It costs a lot to get a second opinion, which of course I need, and in the meantime I'm taking it real easy, and I did get my psychiatrist to give me Lyrica since no other of three docs would address my pain, which that drug is the first time in years that my low back felt halfway decent...but I'm even afraid of that, because what if I'm masking the low back fixing to give-way?
