I would suggest that you take your test results, i.e. MRI, xrays and get another opinion for another spine specialist.
If you haven't been seeing a spine specialist then you need to do so as soon as possible.
Radiculopathy does not always mean damaged nerves. It can also be compression of nerve or nerve roots that is causing the pain.
If you have an attorney and the attorney is not working for you and helping you to get WC to pay for the treatment that the doctor has said you need, then you need a new WC attorney as well.
Are you sure your attorney is a WC specialized attorney?
You need to fight WC which can be a very tiresome process, but if you do not give in to their treatment of you, or better stated lack of treatment, you will not get the help that you need.
Good luck
