There are further tests that might help confirm that there is a problem. For instance, with vascular disease, there might be confirmation that is done not only with more fancy doppler tests that we had discussed, but also maybe a fancy kind of x-ray of your blood vessels called an angiogram or a device like an MRI that can do similar things in different parts of the body to assess this or a special kind of computed tomography or CT angiogram. These are things that could be done if there was a concern of a vascular blockage. If there was a concern further, neuropathy almost always can be checked pretty darn well in the clinic itself and it's unusual to go out for further exams, but you might get something like a nerve conduction velocity or even a skin biopsy to look for the amount of little nerve fibrils in the scan.
