Your situation is much more complicated than others because you later suffered a concussion, but chiropractors hurt a lot of people if you don't find a good one. There is little evidence they help a whole lot. I've seen chiropractors, I'm not personally against them, but one hurt me a lot by giving me a physical therapy program that was supposed to be less time consuming than the one I've been laboring with for hours a day I got from actual physical therapists, but ended up, as I say, hurting me a lot more than I was. Chiropractors do a lot of things they don't study in school but pick up on their own. The only thing they really learn in school is how to do spinal adjustments, and then once they get their degree they can do anything they want even if they don't know how to do it well or if the technique is on the dangerous side. Traction has been known to harm people. it's not really used a lot anymore. Getting people moving rather than immobilizing them is now considered more useful for most people. It may be what your chiro did harmed you. The concussion certainly didn't help. Neurologists aren't really the people to see about this sort of thing, they deal with nerves and the brain. You probably should be seeing an orthopedic surgeon, as they will be better at having you move around so they can see what hurts you in addition to the diagnostics tests, but that being said, this stuff is really hard and the diagnostic tests aren't great at seeing what's wrong. For the concussion the neurologist was the person to see, but for whatever the chiro did and the original injury an orthopedist is probably more appropriate. I have no idea what happened to you, unfortunately. Peace.
