9 yr old with spinal pain

My son who just turned 9 fell about a year ago on his neck while doing summersaults on the bed ;-( It just burned and hurt at the time but since then he complains ALMOST DAILY of severe pain from his neck to the tailbone and lately his thighs and shins too. I do not believe he is lying or making it up. Topical arnica oil or oil of oregano helps or he will sleep with a hot water bottle.

He's had chiropractic/ND care since birth and I have taken him to 2 chiropractors and an alternative MD. No one seems concerned. The altnrative MD suggested a german homeopathic iron. It's been a week and there is no change.

He is very sensitive to foods and he has never had junk food, pop, chips, chocolate bars or anything like that. However we also avoid foods the last 4-5 years like wheat, dairy, corn, soy, yeast as he gets diarreah, nosebleeds, rashes on his lip, headaches, leg aches. He appears to have the same pains as I do to the same foods.

The pain is WORSE at night, in the soft bed. Hard floor helps. (there is no urinariy infection present)

Pain is mostly 'the whole spine' but can also be on both sides of the spine.

He urinates alot during day. Sometimes 5 minutes after the last time he went. He never gets up in the night to urinate. But is scared at night and most of the time we all sleep in the same room (we have several beds) especially since someone tried to break into our home recently in th emiddle of the night-we have an alarm now which has accidently gone off a few times and scares us all to bits!)

No thirst. cold alot.

Can't get him to sleep at night.

Can't get him up in the morning!! groggy and grumpy in the morning.

angry alot lately (oats make him really angry!), back talk, sad, frustrated, can't express himself.

He is really short for his age (I recently started supplementing with cal/mag/d, c) but he's fast and nimble and overall an amazing and responsible child. Fun with his little brother! Fights with his younger sister though! He (and his 2 youngr siblings) are homeschooled and we live in the country and he has lots of chores, animals, responsibilities. Lately though I have felt he is overwhelmed since he started lying about collecting the chicken eggs (he only gets half or throws th others in th bush) or if I ask him if he lockd the door, or put the laundry in he will say yes, but then I realize he has not done it. I never used to have to check, now I do. He has taken his dads cell phone in secret because he wants to play on it and then lied about it. We have JUST started to allow them to watch a bit more TV where we hardly have in the past.

His dad has been laid up in pain this last year and it's been hard on ll of us, especially the kids, they comment frequently at how grumpy he is- my husband is almost always laying down as soon as he comes home, for hours and hours on end ;-(

My son frequently says he wants to be anywhere but home...the neighbours, my sisters, skating etc. Can't blame him ;-(

Would love some suggestions....

Thank you
