War injury back, neck, head

About 3 years ago while serving in Iraq I was injured in a vehicle. I was in a weapon turret and was slammed backwards (basically bent completly backwards just under shoulder blades). I also got a concussion. Since then I have constant back problems that form basically up and down my spine and a constant aching under my left shoulder blade. I have been given multiple tests to include x-rays, Mri,s and others. I have had a few different diagnosis from nerve damage, to dislocated rib near spine (chyropracter), to even "We can't find anything wrong". I am not imaging this pain and it has left me with constant uncomfort and when I physically exert myself I am aching for days. Headaches are almost a daily occurance, and even recently I have had some vision problems. The one who told me they did not see any problem was a specialist for backs out of Omaha. What do I do? I cannot keep going through the constant ache and headaches.

so sorry for all your pain, so frustrating that we need to see so many doctors b4 a correct dx can be given!!
I would persist with other doctors that specialize in orthopedics and neurology....sometimes it can take many years and many doctors (even ones in the same field of study) b4 u will get a true dx....
keep pushing for more referrals from your GP do not give up, it isn't fair to live in constant pain. Are u on any medications for pain relief? If not I would also ask to see someone who specializes in pain relief. good luck
