Joann- do you have a work comp atty ? or your own doctor to be on your side?
you sound like you really need to find a good comp atty - the pay for them comes out of any settlement you might get.
look on your state website for workers compensation and the info there.
interview comp attys before signing with them some are better then others.
make up a list and a time line of your injury and pain, symptom's, tests.
take that and any correspondence from employer & comp ins carrier to the atty
atty should be able to steer you to a good Dr.
