If you�ve had one or more symptoms that are common with MS, your doctor may suggest tests. These can include:
�Blood tests to look for other problems with MS-like symptoms, like Lyme disease
�A test to measure the speed of signals traveling along your nerves
�An MRI, which creates images of your brain, so your doctor can check for damage
�A spinal tap to check the fluid in your brain and spinal cord; this may show signs that your immune system is harming your nervous system.
