i agree with the others, get insurance
first, as it can get very expensive. An MRI
alone is over $1,000. I had an ultrasound done to r/o cardiac problems and my share was over $800. Then, because you want insurance first, our medications are VERY expensive and some run in the thousands per month.
Not trying to discourage you but you've gotten some good advice above, just don't expect to walk in and out of testing with a diagnosis!
