I'm having full body pain, what could it be?

I've now been suffering for sevire body pains from my back all the way down to my ankles I have quite a good pain barriar so you might understand how much it hurts, im only 15 so im not shure whats wrong, I've been to the docs quite a few times they...

just dont know I've been to the hospital and had a blood test and that didnt show anything

my symtoms are, my bones are always cracking exspeshaly my neck and knees, I cant hardly walk because of the pain

it all strarted with my back and times gone by its moved all around my body
and yesturday I went to the out of hours docs becouse my sineses and head were hurting and I kept going dizzy

please somebody help its getting unbearable

you need to convince the doctors that something is wrong just have them take tons of x rays because if your back is hurting its really bad

I was watching dateline a few weeks ago about someone who was in so much pain she couldnt walk go to datelines website and look back untill you find what your looking for
or web md?

hmmm
if I might take a blind shot at this:

you might have herniated discs in your cervical and lumbar vertebrae (or if I may dumb it down, the vertebra in your neck and your lower back) this is when the soft material between the vertebra is pushed out and its touching your sciatic nerve (which should explain the knee pains, a common sign of lumbar hernia)

and the blocked sinuses and headaches would be caused by the cervical disc hernia

you should immediately ask for an MRI or CAT scan
its the only way you will know for sure...

even if its not hernia its DEFINITELY a problem with the spinal cord

you have to immediately do something before its too late...

Google WebMD Symptom Checker :]
It's very helpful

first off this isnt a joke
you dont just tell someone to go to datelines or check out a useless application that does nothing to help.

secondly its sad to see, you actually are being serious... and frankly there is better advice to give than check on-line, please educate yourselves

I'm sorry... :[

Anyway, I'd probably do what sisterfeather said, get some xrays
