I am sorry to hear of your misfortune.
Talking about chiropractors, since we are on this subject...I will go off on a tangent.
Hearing stories like this gets me upset.
Chiropractic, as a profession, is somewhat divided (but the public doesn't really know about this).
You have "straight" chiropractic, and "mixer" chiropractic.
Straight chiropractors believe, in a large sense, that the primary role of a chiropractor is to adjust the subluxations found in the spine and the body will heal itself.
Mixer chiropractors believe that, yes, subluxations do exist, but there are other factors involved, such as muscles and soft tissues, nutrition, disease processes, disks, joints, etc. The mixers also recommend MRIs and work with MDs, including requesting labs (blood tests and chemical profiles) in an attempt to find out what is wrong with the body.
There are some chiropractic colleges that instruct "straight" chiropractors, and there are some that follow the "mixer" model.
The "mixers" are put through thorough training in diagnosis, anatomy (including a complete dissection of the human body), radiology, and physiotherapy. The students are also taught how to read EKGs of the heart, how to read blood test results (and what they mean), how to read and analyze blood chemistry test results, and others.
Many of these students actually "forget" about the "adjusting" component of their care procedures because they are drilled so hard on what the MDs do so that they are prepared to work with them and know when to refer.
As far as straight schooling, I am not familiar with their curriculum, but I can share that chiropractors must pass national board examinations in order to get a license. Some students from the "straight" schools have difficulty passing these boards because they are tested on diagnosis, microbiology, anatomy, and biochemistry, which are not heavily covered in some of their curriculum.
So, I hope that helps you all understand why there are some great chiros out there, and why some can make some huge mistakes that cause more pain, unfortunately, to some of you out there. Not all are equal...
