Ok, so BciPam has a bad opinion of Chiropractors, to each his own, but there are plenty of bad MDs, PAs, and PTs out there too. Simply put, I love my chiropractor.
Mary, if your insurance doesn't cover chiropractors, you might want to look into seeing a DO, Doctor of Osteopathy. They go through the same training that MDs do, they take the same board examinations, they are surgeons, orthopaedists, radiologists, cardiologists, all of the -ologists that MDs are, but they go through an additional type of training called Osteopathic manipulative treatment which is a hands on approach to diagnosing and treating all kinds of symptoms. Most insurance plans will cover DOs since they are essentially identical to MDs. Check out http://www.osteopathic.org/index.cfm?PageID=ost_omt for some information. I can't imagine being that type of debiliating pain for months waiting on an insurance company. This might be an option to get you some helpful treatment while you're waiting for an MRI. Best of luck!
