So my neurologist had ordered me to get a mri done for my neck and i just wanted to know should i still get a second neurologist?

It mainly depends on what is going on with you and what the physician is considering as the cause. If you are seeing a neurologist it may be because you are having problems with numbness or tingling or weakness in one or both arms, for example. If so, one cause can be pressure on nerves or even the spinal cord in the neck which will not show up on an x-ray.

There are many reasons why a second opinion might be appropriate, such as questions of diagnosis or therapy, and need for confirmation of a confusing clinical presentation. Often the additional opinion can reassure and place all into a logical conclusion.
